Just some thoughts on it.

If god created the universe, than theoretically it would “exist” outside of the universe, and so could not be measured or detected by human standards. But, if it did exist, than why would it be a part of our world in biblical times, and not present times?

Why fight over who’s imaginary friend is the best when it might be the same? Perhaps a deity does exist and revealed itself to all of the different peoples, and they interpreted it differently? Of course, people have a natural tendency to try to explain things, and supernatural explanations are easiest, so perhaps everyone just made up explanations on thier own.

Why do holy books have special rights just because they were written a long time ago? The authors are unknown. If I wrote a book and buried it, and people found it a couple thousand years later, would they have a reason to believe everything in the book?
