Silly Atheists.

[Aoi Magi]

And so whether Quran is that book or not, at least, acknowledge, that if God exists, he can prove things and not only that, but prove all that he speaks, and only speak things that are proofs of his and that will give insights through reflection.

*bold mine

Fine! I acknowledge that "if God exists, he can prove things" but since he hasn't been able to prove his existence till date, your God doesn't exist.
