The "life from Mars" fanatics make several leaps of faith in imagining Martian "space seeds," full of viable bacteria, raining down from our skies. �If we accept that the solar planets are all basically the same age, and life first appeared here a few hundred million years after Earth's formation (the planet was still "hot" at the time), then this is a pretty small window for a LOT of activity. � The infant Mars would have to evolve a hearty bacterial population, suffer a catastrophic impact that ejected bacteria-laden stones back into solar orbit, and those "infected" Martian rocks would require several million more years of space migration to the Earth---and all of this would transpire in the solar system's first few hundred million years of existence? �I'm not saying it's impossible; rather, I'm saying that this is a scenario that is supported by not one shred of evidence.
