There are more things in heaven and earth…
From the endlessly entertaining Conservapedia:
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 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.
Emphasis added to highlight teh crazy. Well, the extra-crazy, anyway.
Hydroplate theory is an actual, honest-to-goodness bit of scientistical crackpottery, embraced by some young earth creationists. The Mars angle, though, elevates it to an entirely superior level of risibility.
How did the slurry travel to Mars? On unicorns, of course! Duh!
