Q. My question is that how do we deal with atheists? What is the best thing to do?
A. Typically, we should avoid debating with hardcore atheists. Most of them, have religious affiliations and they are systematically trained to believe in atheism. Their belief is more on sentimental platform then sheer philosophy and they are often stubborn. To those who are open tell them that if there is no God who created the universe and life. If they say it came by chance or nature ask them what is the practical experiment that has proved that theory.
There is none. No scientist ever got a Nobel prize for creating life in lab and none created universe in lab either. If they are open then its worthwhile to debate, other wise let the school of hard, knocks teach them.
