If evolutionists don't have to prove anything, then neither do I.
lol...cop out much? You can't prove God exists, so just stop trying. BTW, did you even watch the giraffe video? If you did, I'm sure your brainwashed mind went something like this: "God made it that way so we would question his existence, it's all a test and it takes faith." Hooray for ignorance==religious beliefs.
Evolutionists don't ascertain that what they THINK happened is true. Observations are made of the world that surrounds us and hypothesis' are formed. Then the hypothesis are tested until evidence is found whether or not it's true.
Religion OTOH, tells you that 100% they are correct (of course EVERY religion is correct). No questions asked, if you do then you're a doubter not a true believer.
