What Do You Have to Say for the Agnostic?

I believe everyone deep down inside, he says. What do you have to say for the people who might be atheists agnostic? Even though I personally don't believe there's such thing as a true atheist. If they're sincere, they'll come to it like you did. You started studying and really growing knowledge. Now tell me what do we know that separates Islam from all the man-made religions? There's so much in that.
