See...it doesn't work that way. If you believe in God you have the burden of PROOF on you to PROVE God exists. Science doesn't need to disprove God's existence. There is no burden of disproof. Science can prove many things exist or are true with data and experiments. The lack of data doesn't necessarily disprove something...it just shows there is no data to prove it. In other words Science doesn't say (or prove) there is no God....it just says there is no data to determine (or prove) there IS a God.
The sad part is, science can be proven and seen, God cannot. If I came up with a book about an animal I had no proof existed, would you believe me when I said that it is definitely there? Didn't think so.
