frankly I'm growing tired of people saying "science/evolution/big-bang requires the same faith that creationism does". bullshit, there's a BIG difference. any leading scientific theory, whether or not it's complete, is still based on a certain amount of evidence. intelligent design/creationism isn't based on evidence, it's based on other theories lack of evidence.
If I just had a nickle for every time somebody started an argument for "proof" with "well how do you explain.....". doesn't matter how people explain it, doesn't matter if they can. just because you can't explain it doesn't give god the credit by default. creationism is only possible when you present a hypothesis as a fact. IE:

Question: where did life come from?

Bob: evolution. here's my reasons why, here's the evidence we have so far.

Jim: god. my reason being that evolution is wrong here, here, and here, so it can't work.

which of course is just silly because the failure of one hypothesis does not validate the other.
