The concept of God is agreeably a rather abstract idea of Someone who supposedly exists. I can definitely see both sides of the story here. I, for one, believe in God's existence and the events and historical happenings from the Bible and that all those people existed at one time. But to a secular viewpoint, why should they believe a book that is thousands of years old just because it has a cult following and "discredits" (what) science?
Just by that question, I've investigated a few strange implausible events from the Bible that seem to contradict science or Earth's apparent history. In most scenarios, there is usually a logical explanation. Even if I didn't identify as a Christian, I'd still consider myself to be a catastrophist (young earth).
