By nature man is rebellious. So rebellious, in fact, that he has to have this “conscience” that decides what is right and wrong for him. And what’s right for me is wrong for the next person (based on our upbringing). So please do tell me ... why did man create a Being greater than himself to tell him what he needs to do when, quite frankly, man doesn’t like to be pushed around ... especially by someone that you cannot presumably see?
What good did man see when he created a god?
For purposes of this discussion, let's assume that there was nothing once upon a time. And this nothing was intelligent enough to reproduce itself and everything else we see today (which then begs the question, if a self-reproducing independent organism could replicate itself, why create gender in the first place with women being child bearers? Why didn’t the organism just leave life as self-producing (like trees and some reptiles are?)
And then, furthermore, if this organism was so smart that it could create galaxies that go to the n-th power and create the sun, moon, stars, rocks, planets, why create life (be it trees, plants, animals, fish, etc.) on this planet? And on no other planet? I mean, really - is this planet that significant to one organism that came from nothing? Anyway, I’m detracting.
Of course, this reproduction process took millions of years to get us to where we are today so that nobody can really really prove anything (everything is based on assumptions and theories and dating models that we think are correct). We then turn our focus to man’s evolution over the past two hundred thousand years.
If Wikipedia’s timeline of homo sapiens' evolution is anything to go by, modern man is a pretty new species, with modern humans being only 200,000 years old. But religion is, at best, 6- to 10,000 years old (depends on your source). So why would modern man (called hunter-gatherers) live for 190,000 years with some meager developments such as burial tombs, pitchforks, axes, stone hunting tools, jewelry, the wheel ... and then, one day, just wake up and say, “Today, we shall make god!”
Religion – any religion – is at most 10,000 years old. So man lived for over 190,000 years and one day just got up and created a god. Why? What did man do for 190,000 years when there was no god? Why is there no historical evidence of a god prior to the recorded beginnings of the earth as in the Bible? And please, having records of burial sites does not denote the existence of a god - even atheists bury their dead!
