As to the evolution thing, yes, there may have been a 1 in a 129,083,420,985,985,609,835,679,835,769,058 chance or whatever, but remember that something had to happen, and there is an equal chance of each of those things happening.
so, it is actually not that amazing we are here.
for example, if i have 3 dice. i have a 1 in 216 chance of rolling 3 sixes (6*6*6). I also have a 1 in 216 chance of rolling a 1 a 2 and a 3, or any other combination.
Evolution is kind of the same, but it is more like rolling 500,000D400,000,000. We dont know however if what we have is like rolling all 6's, or not.
oh, and to the dude who said "IIRC, Jesus was born in AD6' or whatever, you must be real old if you remember that!!!!
