Is There Life After Mars?
Ernest Samuel Llime - Woodhaven
The Viking mission, having landed on Mars quite
some time ago, has shattered the dream of millions; all the people fond of
Percival Lowell’s vision of “networks of canals” and Martians living on the red
planet. Alas, the probe’s evidence, “ . . . seems to weigh against finding even
microbes there.”1 Nevertheless, the possibilities seem endless; after all, Mars
is just a stone’s throw away from Earth. The Universe however, though perhaps
not infinite, is of an almost incomprehensible size. So what else could be out
there? And is it intelligent?
There seem to be three different groups with three seemingly different answers
to these questions, involving three very dissimilar ideologies. Interestingly
enough, they are all affirmative in spite of their unequal and contradictory
nature of their basic assumptions. Even though this paper is concerned mainly
with the scientific point of view, it is only fair as well as a part of the
scientific process of investigation, to dwell somewhat on the other views. It is
also fair to point out that the Scientific Method is going to be employed in
looking at the evidence, since it is the only one that can prove its
workability.
The first group that is going to be discussed can justifiably be called the UFO-logian
group because of its association with those kinds of phenomena. The UFO
(Unidentified Flying Object) is a generally accepted acronym for a series of
(thus far) scientifically unexplainable events. In most cases the (photographic)
evidence is of very bad or (written or verbal) mystical quality, and it is
without exception unpredictable and non-duplicable. The bad quality of the
evidence and its sometimes mysterious disappearance are explained away as
results of the activity of space people (the UFO crews) because for instance, “
. . . they would find some people worshipping them as ‘gods’ which they would
not allow.”2 or by some sort of official plot, “[Captain Edward Rupert] . . .
said he had been ordered by the Air Force to destroy any reports that looked
authentic . . . "3 In a lot of cases, space people have been reported as having
been seen, and even having carried conversations with earthlings, “I have had
other saucer experiments, some with space people directly or face to face . . .
“4 is an example of that. Another one involves a conversation between a
gentleman named Jack Schwartz and an alien, that took place in the latter’s car,
“ . . . we come from a tribe of people who crash landed in a rocket ship on
Earth thousands of years ago.”5 “E.T.’s” do not seem to like being photographed
and no clear pictures of them are available; in a lot of cases they reportedly
disappear, as in the case of Mr. Schwartz, who lost contact with “XB-15” shortly
after their conversation.
A number of loosely related sub-groups make this one up but they are basically
similar in kind and their differences are mainly in the type and degree of
importance and/or mysticism that they ascribe to UFO’s.
The second group is much larger, most probably the largest group of people that
can be included in any one loose association; it is composed of individuals who
believe in a non-mechanistic creation by a higher entity, a creator. This group
can certainly be called the religious group and it is included in this paper for
two reasons; one of them is that their most basic tenet, the existence of one or
more gods, is actually answering our main question affirmatively and without any
shadow of doubt. After all, one or more gods (depending on the individual
religion) have created the Earth and even the Universe and therefore, by
definition, they are most certainly of extraterrestrial origin. If the number of
supporters were to be considered the deciding factor in accepting it, then this
should most certainly be the prevailing one. This group is divided into more
faction and sub-groups than any other and one of them is the second reason for
including it here. The faction in question has been very active in the United
States lately in advocating a pseudo-science called creationism. This is an
important topic because of its relevancy to the subject, and because it is
actually employing the Scientific Method in trying to disprove many of science’s
discoveries.
Robert V. Gentry is one of the scientists who subscribe to a creationist view of
the Universe. He is involved in researching the halo rings left in various rocks
by radioactive isotopes; his research leads him to believe that, “ . . . the
Earth may only be on the order of 10,000 years old – a factor 4.5 x 105 smaller
than the age most geochronologists give it.”6 It appears that his research is
very well regarded by his colleagues and only his conclusions are disputed.
Nalin Chandra Wickramasinghe is another creationism believer; his background is
very different from Mr. Gentry’s and so are his views. Mr. Wickramasinghe is a
Hindu raised in Ceylon (now Sri Lanka) and he says, “ . . . he doesn’t even
share the basic premise of the Christian faith, much less the Christian
fundamentalists’ trust in the general ‘inerrancy of the Bible in its original
autographs’.”7 That is actually Mr. Gentry’s belief and it is probably mentioned
in the original, in order to point out that this is indeed a different opinion
on the subject. “Mr. Wickramasinghe currently heads the Department of Applied
Mathematics and Astronomy at University College in Cardiff, Wales. And for the
past 20 years, his work has tended to focus on inquiries into the possible
composition of interstellar dust.”8 He is quoted as saying, “Two years ago, Sir
Fred Hoyle and I reached the conclusion that a whole body of astronomical data
pointed to microorganisms being present on a colossal scale in space – some
1052individual cells being present in our Galaxy.”9 Mr. Wickramasinghe is
further saying that, “Other experiments using ‘contamination-proof’ techniques
identified 17 amino acids within the Murchison meteorite;”10 Amino acids are
some of the building blocks of life and, based on that, and on the detection of
living cells in the Earth’s upper atmosphere, he is concluding that life came to
Earth from outer space. When speaking about evolution Mr. Wickramasinghe is
saying that, “ . . . the probability of discovering this set of conditions
crucial to life by random shuffling is one in 1040,000, a number that exceeds by
many powers of 10, the number of all atoms in the entire observable Universe.”
(Therefore, he is,) “ . . . compelled to seek a non-mechanistic ‘creator’ for
life.”11
Both scientists have testified in a court of law, on behalf of Arkansas, in
defense of creation science. U.S. District Judge William Overton has, “In his
opinion of the case issued Jan. 5, [1982] concluded, ‘creation science is not
science’.”12
The research mentioned by Mr. Wickramasinghe has been undertaken by H. D. Pfulg
of the University of Giessen in West Germany. At the time of the article, the
results, “ . . . are to be published soon.”13 The data are quite valid and will
serve to introduce us to our third group, the scientists. They have a lot of
circumstantial evidence and well thought out theories but, so far, no direct
data on the existence of extraterrestrial intelligence. The line of approach
pursued by science is based on the premise that, this kind of life would have to
mimic the development of life on Earth; this is mainly because of the fact that
Earth life is the only kind of life discovered so far and therefore, the only
measuring stick available. Thus, one of the first necessities for our kind of
life is a planet. “We have to assume . . . that complex life must grow and
evolve to intelligence on planets orbiting stable stars.”14 The detection of
planets orbiting other solar systems, is a very difficult task however, in the
words of David C. Black, “We now possess the technological capability to mount a
comprehensive search for other planetary systems.”15 Such searches have been
going on for a while on a smaller scale, and of all the stars investigated to
date, the most promising one seems to be Barnard’s Star; A study of the shift in
the star’s center of mass conducted by Mr. Black together with G. C. J. Suffolk,
“ . . . assumes three planets for Barnard’s Star.”16 And so, it seems that even
though no planets have been observed outside of our solar system, their probable
existence is a generally accepted scientific fact.
Other relevant investigations are the ones being made into the possibility of
spontaneous life generation; even though we have seen some evidence that seems
point to the existence of life in places other than Earth, which is still not
conclusive enough. Also, it does not offer an explanation for life and therefore
somewhat suspect. Many experiments on the generation of life have been conducted
so far; Speaking at a conference on communicating with extraterrestrial
intelligence (CETI), Carl Sagan is describing such a series, “ . . . with this
encouragement we can do the experiment one more time and mix together a mixture
of methane, ammonia and water, supply it with energy and see what molecules are
constructed.” (And later on,) “ . . . a wide variety of such experiments have
been performed . . . and what we find is that not only are amino acids made in
high yield but also the nucleotide bases and sugars, and indeed all the small
fundamental building blocks of biochemistry.”17
Mr. Sagan is presenting a formulation of the “ . . . number of technological
civilizations in the Milky Way at or beyond our level of technological
advance.”18 The formulation as devised by Frank Drake is as follows: N =
R*fpnef1f;fc1. 19
This formulation is the central issue of the CETI conference and its factors are
discussed at length by an international panel of scientists. The applicable ones
are: the rate of star formation averaged over the lifetime of our Galaxy, the
fraction of stars which have planetary systems, the mean number of planets
within such planetary systems which are ecologically suitable for life, the
fraction of such planets on which the origin of life actually occurs and the
fraction of such planets on which intelligence arises. (For a fuller
development, please refer to the proceeds of the CETI conference.) This formula
is revealing the extent of extraterrestrial intelligence. Most of the factors in
our formula can only be replaced by probable figures; at the present time these
probabilities are not even statistical because we do not have any data at all on
some of them. What we are talking about are subjective probabilities; their
nature is defined by Terrence Fine thus, “The subjective view . . . encourages
the holder to use his informal judgement, beliefs, experience in arriving at
probability estimates . . . “20 In a summation of the conference which expresses
very nicely science’s position on this matter Mr Fine says, “We would judge that
the concept of subjective probability is at present the only basis upon which
probability statements can be made about the extraterrestrial intelligent
life.”21
In conclusion, the shortness of the UFO section may seem strange but that is not
for lack of written reports; on the contrary, this kind of literature is
available in enormous quantities and there are even specialty book stores that
deal in UFO writings exclusively. Nevertheless, the two samples used are typical
and explanatory; space people can be talked about but their existence cannot be
proven as yet, they have to be seen in order to be believable.
The religion section is somewhat longer but fairly poor in religion per se. The
reason is very similar; a creator’s existence cannot be proven yet either, and
existing evidence can at best be described as circumstantial and given to
different interpretations. In addition to that, the mystery is what makes God, a
God and not just another ET. Also, one of the basic requirements of most
religions is faith without inquiry.
And thus, again, we come back to the Scientific Method; it may not be the best
possible system of thinking, but it is the best humanity has so far devised for
coping with natural phenomena. Also, it is the one that can devise working
models, of situations and events, which are taking into consideration all the
known factors that are relevant. And most important, it is the only method of
basing conclusions on evidence that is measurable, and on experiments that can
be duplicated. As we have seen, is on the verge of proving the existence of life
in outer space and it has certainly accepted the possibility of extraterrestrial
life. The search for it is an ongoing task and the proof may not be that far in
the future.
