I don’t disagree with you ya akhee, but what I’m trying to say is that the most common argument to start with is also found in the Qur’an. What would be the first thing you would ask an atheist: who created you or did you create yourself or did you come from nothing? Wouldn’t you be asking him/her one of the above questions? If so, then there’s nothing wrong in quoting the Qur’an to present the argument in more profound style. As far more logical arguments, then I’ve already covered those in the the link i posted earlier: Does Allah (God) Exist?
btw, I don’t agree with you that we believe in the Qur’an due to blind faith. We believe in the Qur’an because we’ve rational evidence for it.
