Believers are always pushing the idea that God exist, my question to them is Where is God?
If a question is ask about the existence of aliens our mind would ask for evidence so why treat the subject of God differently? why do they believe in God w/o any substantial evidence in their hands?
again here is the challenge..present your evidence that there is a God.
if you say to an american that a fruit named durian exist, for him to believe your words, the easiest way to make him believe you is to bring the fruit to him.
