Quran As A Proof For Existence Of God
As for your question regarding what approach we should have with people who do not believe in the existence of God, I think that it should only be a straightforward approach of explaining to them the basis of our own belief. Those of them who are sincere but only fooled by the misleading claims of popular science will find more than enough weight in our argument. However Quran verses 6:109-111 are very clear that those who do not want to believe, there’s absolutely no proof that will satisfy them.
