Changes

Currently the most exciting subject for speculation concerning extraterrestrial life is the planet [[Mars]]. Its atmosphere is quite thin, and this would militate against the presence of life or, more to the point, the presence of standing or flowing water. But photographs taken from orbit and from the surface of Mars reveal erosion channels that strongly suggest that water once flowed on Mars. Indeed, the first graphic above shows changes in a gully in two views of it, taken four years apart--as if liquid water had opened another erosion channel in the meantime. (The operators of the Mars Global Surveyor insist that such pictures might still contain artifacts that make them unsuitable for scientific research, and hence disclaim any definite conclusion that anyone might be tempted to draw from them.) The second graphic shows a [[meteor]]ite, found in [[Antarctica]] in 1984, containing microscopic cavities that once might have held [[microbes]] and that, until recently, was believed to have fallen to earth from Mars.<ref>Donald L.

If one could show that abiogenesis occurred on Mars, then that process was far more likely to have occurred on earth than it would be absent such a showing or finding. Yet apart from the reliability of such evidence is this one inherent weakness for this argument: it assumes that life ''found'' on Mars ''originated'' on Mars. The [[Hydroplate theory]] of the [[Great Flood]] suggests that large quantities of water, including muddy slurries, were ejected into space during the initial fissure of the original earth's crust, and that these ejecta persist today as [[comet]]s, [[asteroid]]s, and [[meteor]]oids. If such ejected water and mud fell to Mars from above, then they might have held [[microbes]]--and therefore any microbes found on Mars are far more likely to have come from earth during the Noachic Flood than to have originated on Mars.<ref>If such life forms survived, that need not be a great shock to any observer. [[Extremophiles]], or microbes known to thrive under conditions that would kill or render dormant any other form of life, are well-known on earth and have even been the subject of engineering studies attempting to find practical uses for them.</ref>

Space scientists have searched for extraterrestrial microbes for years. To date, no definitive proof of such microbes has been found. The Antarctic meteorite mentioned above, and the alleged bacterial fossils on it, fueled speculation for months, until other scientists finally determined that the microbes involved probably were earthly contaminants.<ref>Rick Lockridge, "[http://www.cnn.com/TECH/9801/15/contaminated.rock/ Scientists dispute NASA's claims about Mars meteorite]", ''The Cable News Network'', January 15, 1998.

The middle twentieth century introduced other now-familiar themes, often through the media of comic books, novels, low-budget films, and [[television]]: humans caught up in events on other inhabited worlds, spacefaring starship crews, and extraterrestrial "prophets" appearing on earth with either good intentions or bad.  By the late twentieth century, big-budget films repeated these themes and introduced new ones, sometimes (as in ''[[Star Wars]]'') bypassing Earth altogether in favor of mythlike tales of ancient civilizations. The alleged crash of an extraterrestrial scout craft near Roswell, New Mexico, United States was the subject of another film.

The [[Star Trek]] television franchise created by [[Gene Roddenberry]], with its myriad of extraterrestrial and often trans-galactic nation-states and empires, hardly needs introduction. Producer Quinn Martin created a series that centered on one man's attempt to warn his government that certain people were not what they appeared, but were instead extraterrestrial spies. More recently, Kenneth Johnston created a concept (''V'') of a spaceborne force whose commanding admiral and officers at first puts on a friendly appearance similar to that of [[Matthew Perry]] (the American commodore who first visited [[Japan]]) but, soon afterward, subvert human governmental and media institutions in order to further their true purpose, which is to steal earth's water and carry away earth's population for food.

The ''[[Star Trek]]'' television franchise created by [[Gene Roddenberry]], with its myriad of extraterrestrial and even trans-galactic empires, is well known. Also in the 1960s, producer Quinn Martin created the series ''The Invaders'' that centered on one man's attempt to warn his government that Eath had been infiltrated with extraterrestrial spies. More recently, Kenneth Johnston created ''V'', a series in which a spaceborne force whose commanding admiral at first puts on a friendly appearance (similar to that of [[Matthew Perry]], the American commodore who first visited [[Japan]]) but then subverts human governmental and media institutions in order to further the aliens' true purpose, which is to steal earth's water and carry away earth's population for food.

Nor have science fiction writers ignored speculation on the finding of extraterrestrial microbes. Usually they have portrayed such microbes as capable of producing deadly extinction-level pandemics. (See, for example, ''The Andromeda Strain'' by Michael Crichton.) John B. Olson and Randall S. Ingermanson, however, speculated that the first crew to fly to Mars might discover incontrovertible evidence of microbial life--including a culturable microbe. This would engender excitement in the hearts of their launch authorites, but would also inspire such fear in the mind of a [[National Aeronautics and Space Administration|NASA]] engineer that she would actually attempt to strand or murder the crew to stop them from back-contaminating the earth with their culture.

Defenders of the compatibility position might insist that neither of the two verses named above speaks directly to the uniqueness claim. But the original [[Hebrew]] and [[Greek]] texts use definite article adjectives and references to a specific person named [[Adam]] (and another, named [[Jesus]]), with no hint that either Adam or Jesus had any counterpart elsewhere in the cosmos. These things militate in favor of uniqueness almost as well as any direct negation of plurality might. Again, compatibility defenders might cite a lack of evidence that any hypothetical alien race would ''require'' counterparts to Jesus or Adam. But [[Christian]] critics reply that if the Bible is real at all, then life does not arise out of non-life. Therefore ''every'' race would have its Adam--and if any given Adam did ''not'' fall into sin, then his race would be under strict Divine orders to avoid contact with humans until the "hour of temptation" (see above) came to pass.<ref>For a further exposition of the uniqueness position, see [[Essay: Extraterrestrial Life and the Bible]].</ref>

The speculation concerning Jesus dying multiple deaths on other worlds has occasionally found poetic expression. See, for example, [[The Innumerable Christ]] by [[Hugh McDiarmid]].

The presence of extraterrestrial ''microbes'' on one or more of the other planets in our solar system (most likely Mars) does excite some fear in Christian quarters. But not all Christians harbor such fear, and even [[Young earth creationism|young earth creationists]] are quite confident that they could explain such a finding. For example, if the [[hydroplate theory]] is correct and a slurry of mud from the Great Flood traveled to Mars and poured itself out upon it, then such a slurry would almost certainly contain microbes. That some of these might be extremophiles, and thus capable of long-term survival even in such a harsh environment as that of Mars, is entirely possible and would allow complete harmony between the finding of microbes in such locations and the Biblical account of earth pre-history.
