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.

Furthermore, no sane space mission planner could in good conscience ignore the potential hazard of the transport of a microbe to Earth and the release of that microbe into Earth's [[biosphere]]. Happily, measures for containing such a microbe, perhaps derived from those measures taken during [[Project Apollo]], would contribute a relatively insignificant amount to the total budget of a program of crewed missions to Mars or to any other celestial body.
