Why do people still believe in the supernatural god ..where there are facts to contradict the arguments?

First of all, its inherently impossible to prove a negative, to prove that god doesn't exist defies all logic and rationality, but that's what the theists rely on.

You're right!! the majority of the people on earth are a part of an organized religion and believe in supernatural entities. Why? The simple answer is that we're 'wired' to believe such irrational worldviews.

I read about some interesting studies of the temporal lobe regions that are 'mis-firing' or giving off 'unbalanced' neuroligical signals. Some of the studies are intrigueing, they can duplicate 'religious experiences' in blind tests of humans.

It was already known that the more primitive limbic system of our brains contain the raw emotion where our religious beliefs spring forth. The development of the cerebral cortex (or the thinking and rational part of the brain) is only a recent development in humans, say the last 40,000 years.

Obsolete genes do not die out overnight, so we'll be stuck with 'supernatural belief' phenomena for some time to come.
