Evolution has all the peer reviewed proof which is why its the current accepted theory.
Creationism has none of that because there is no proof, only belief - which in scientific terms is bullshit.
But what if all of the "peers" have the same bias? In fact, many brilliant scientists have been ostracized for presenting any scientific data that appears to promote the creationist viewpoint. If there was absolute proof that there was an intelligent designer it would be completely disreguarded because based on the "scientific" community's opinion there cannot be such a thing.
As for your claim that creationism is "only" a belief, there is NO proof of evolution either. It takes faith to believe in evolution just as much as it does creation. Why? Who was there there millions and billions of years ago to prove what happened? Evolution is a theory. Please stop acting like it a proven fact. That is not a very scientific way of approaching anything.
What if all the creationists have the same bias? (they do). Biologists and scientists look at the evidence and piece it together. Proof of a designer wouldn't be disregarded, but there isn't going to be any proof, and you don't need it anyway. If there was absolute proof of evolution you would disregard it like you do now. Gravity is only a theory but I don't see you questioning that. Belief in evolution takes faith based on evidence and the facts we have. Belief in god takes faith based on nothing but 'it says in the bible'. "Who was there there millions and billions of years ago to prove what happened?" Who was there thousands of years ago for the creationists explanation of things? And please stop acting like god is a proven fact.
