This statement is just plain silly. First, when sin entered the world, it not only changed Adam and Eve, but all of creation. Why do you assume that science operates the same today as it did before sin corrupted the world? Second, why are you limiting God? Just because science says that something was created millions of years ago, why can't that just be how God created it?
Alternatively, trying to use science to prove God or a literal interpretation of the Bible is just as silly as well. If my faith is increased by a scientific discovery, what happens to my faith when that discovery is overturned?
