Evidence for God from Science

Jlay, Muslims just say that the old testament and the New testament was corrupted by Jews and Christians.

Yes, I am aware of that. So the burden of proof would be on them would it not. Especially in light of all the evidence that confirms the authenticity of the scritpures we have.

Yep agreed !

The oldest (and even some commonly used) copies of the old and new testament are still older than the Koran, so the argument that Jews and Christians corrupted them and the Koran is true makes little sense.

Everyone with beliefs is going to try to defend them, including those of other religions. I would examine those defenses carefully; don't feel wary of the defense of Christianity just because defense for other religions exists.
