It would sure explain where our current crop of politicians came from!
Seriously, i'm surprised that life
here on earth has lasted as long as it has. Wouldn't take much to throw everything into extinction. One small shift in the earths rotation or a good sized asteroid strike would do it.
Although Curiosity isn't designed to look specifically for "life", I think they will find a few more pieces of the puzzle that may lean toward previous life forms. No smoking gun, no Jimmy Hoffa - just enough to justify another trip in the far far future.
Our galaxy and the universe is to big for there not to be other life out there somewhere.
I believe life on this planet could come to an end if the right event or events should happen.
Our civilization's tombstone will most likely read: "Done in by air conditioning"
If a sign of advanced life is found on Mars, and the public finds out, it's hard to predict what the reaction would be, but it would certainly change the way most people think about life and history.
I don't think it would have too much effect on religion, though. Religion survived fundamentalism, and fundamentalism survived the discovery of dinosaur bones, evolution and carbon dating.

And not just bacteria, lets say the rover finds a skull, or bones from a civilization that died out millions of years ago.
If life could rise and perish on Mars, could the same thing happen on earth?
Dont worry, they certainly wont be finding any skulls or any other evidence of more advanced life like that.
But regardless of whether they do find life on Mars or not, Earth can and eventually will become uninhabitable for all life, then it will be destroyed altogether. Its just a matter of will it be 4-5 billion years from now whenever the sun gives out and eventually engulfs the Earth, or will it happen sooner due to man made forces.

Not quite, it's Human arrogance for us to say "man kind could destroy the earth"
at least by today's technology... even if every single Nuclear device owned by every country that has them were detonated at the same time, it would not destroy the earth... nor would it render it lifeless. uninhabitable to higher life forms? certainly. but to kill every last organism on the planet? hardly. nor could we break up the planet sufficiently with current technology in such a way that all it's pieces separate at a high enough velocity that the pieces don't eventually coalesce back into a solid planet.
so yeah - mankind will eventually kill itself... along with most higher forms of life... but the earth and life will go on. at least until our sun expends most of it's hydrogen, and turns into a red giant... which will likely consume the planet or at best turn it into a larger version of the planet Mercury.
