you folks need to think in terms of the big picture. probability mathematics is a fascinating subject of which I know very little. What I do know is that the universe is big....really big, and really really old which means that almost anything that is at all probable will eventually happen in this universe. (kind of like the million monkeys and typewriters thing but much much bigger.
I would suggest you rent the Cosmos series by Carl Sagan and watch it. It's plenty cool and explains a lot, or at least as much as it can. Also check out
Steven Hawkings books as well. Failing that....shutup and fire up another one hit and I am sure you will soon have forgotten...something something...whatever.
