A NASA research team of scientists at the Johnson Space Center and at Stanford University has found evidence that strongly suggests primitive life may have existed on Mars more than 3.6 billion years ago. — NASA, 7 August 1996 (1).
When one calculates the likelihood of life's origin, one finds that it is extremely low. Originating by chance, life anywhere in the universe should be rare. Actually, Darwinists are not sure how unlikely extraterrestrial life is. They agree it's probably rare, but if it is too rare, that weakens the case for its by-chance origin on Earth. Richard Dawkins allows three possibilities: life is likely to arise only 1) once per universe, 2) once per galaxy, or 3) once per solar system (2). Others such as John Barrow and Frank Tipler in The Anthropic Cosmological Principle say firmly, "...the universe has to be as big as it is in order to support just one lonely outpost of life" (3). "...The consensus of modern evolutionists is that the evolution of life on Earth ...is so improbable that it is most unlikely to occur elsewhere in our galaxy" (4). Common sense says that if life begins by chance, it's rare.
Cosmic Ancestry predicts that life will be found anywhere it can get a toehold. If it exists on one planet, other planets orbiting the same star were very likely exposed to it. Therefore, Cosmic Ancestry predicts that other planets within our own solar system should show evidence of life. Now of course, after David McKay's team from NASA published its findings (5), it looks like a reasonable bet that Mars once had life. Intriguing photos like the one above and others, showing what NASA believes are fossilized "nanobacteria," were accompanied by analyses of chemical layers that are best explained by biological activity.
Maybe Mars even has life, today. The evidence sent back from Mars by two Viking Landers in 1976 and 1977 was not clearcut (6). In fact, NASA's first press release about the Viking tests announced that the results were positive. The "Labelled Release" (LR) experiments had given positive results. But after lengthy discussions in which Carl Sagan participated, NASA reversed its position, mainly because another experiment detected no organics in the soil. Yet Gilbert V. Levin, the principal designer of the LR experiment, still believes the tests pointed to life on Mars (7). When the same two experiments were run on soil from Antarctica, the same conflicting results were obtained (LR - positive; organics - negative.) Soil from Antarctica definitely contains life. The test for organics was negative because it is far less sensitive than the LR experiment. The same problem could have caused the organics test on Mars to give a false negative.
It is interesting to remember that before oxygen could accumulate in Earth's atmosphere, all the exposed iron had to rust. During that process, lasting hundreds of millions of years, Earth was also a red planet. Could the oxygen that rusted the iron on Mars have been produced biologically? Could life on Mars have simply "run out of steam" after that stage of its development?
"Cells might not divide... Cells will divide.
"Biochemical pathways might be unrecognizable... Some biochemical pathways might be unfamiliar, as some are on Earth.
"Biomolecules might not be homochiral... Biomolecules will be homochiral, with righthanded nucleotides and lefthanded amino acids.
"Cells might not be necessary... Cells will be necessary. This point -- that any life must have at least what a "simple" cell has -- is the foundation of Cosmic Ancestry.
"Genetic coding might be different... Genetic coding might vary slightly from that on Earth, just as there are minor variations among the codings actually found on Earth.
"Genetic material might be different.... Very speculatively, might the genetic templates even be inorganic?" The DNA–RNA–protein system will be conserved, and martian ribosomes will resemble earthly ones.
Even if life on Mars is just like life on Earth, that won't prove the case for Cosmic Ancestry. It could be taken as evidence for a weaker form of panspermia variously called "impact panspermia," "ballistic panspermia," or "litho-panspermia," in which cells are carried to neighboring planets on the debris ejected by major impacts (11). (This idea was prominently mentioned following NASA's August 7, 1996, announcement — maybe life originated there instead of here.) Ignoring panspermia altogether, martian life with the same system as ours could be used as evidence that the origin of our kind of life, from chemicals, is easy after all. The Darwinian paradigm is tenacious.
One benefit of the recent analysis of the Mars meteorite is an improvement in methods of analyzing meteorites for the presence of fossils. It would be interesting to use the new methods on carbonaceous chondites — meteorites not from Mars but from spent comets, most likely. Examples are the Murchison, Orgueil, Ivuna or Allende meteorites, where earlier researchers using older methods have already seen what they believed to be fossilized microbes. Fortunately, this effort is already under way, with very interesting results announced on July 29, 1997, in San Diego, by NASA scientist Richard Hoover (12).
