When we were born, we were automatically trapped within a culture with a certain belief system. This shapes how we understand all things around us. In most cases, it also dictates how we should behave. It pervades our whole personality so much that when it is challenged and we realize that something is wrong about it, it can  shatter our orderly understanding of the world and leave us utterly confused.

If there ever is a God, he is probably hiding himself sufficiently enough so that our innate insatiable curiosity may lead us to investigate how he made the universe, the galaxies, the stars, the planets and life. The excitement will be ruined if he'd just appear and say, "hey! stop thinking about it, I made everything"
