Answer this:
Was the Earth created by God 6000-7000 years ago?
Was the universe created by God in 6 days?
Did God create man from dirt?
Did God create the first woman (Eve) from Adam's rib bone?
If the answer to any of the above is a resounding YES, then we have nothing to talk about. You just need to double your medication and stay away from guns or heavy machinery.
There are two more school of thoughts agnostic and gnostic.
* Those who believe God require to "believe" in things/explanation mentioned religious book. To accept something without any proof without verification is to Believe. This causes problem for people who have habit of logical thinking and verification. All religions have different set of believe about God and relation of God with other.
* Those who don't believe in God doesn't have explanation or answer for many phenomenon like How universe was created exactly. Interestingly those who accept this that they don't have definitive answer and are working on the same.
