Archaeology supports the Bible’s history about the human race being polytheistic from the 3rd millennium B.C. Following the lineage of Noah in Genesis 10 and 11, we see that the human race spread out after the confusion of language at Babel and moved to many parts of the earth. There the families of man worshipped many gods.
As far as we can tell from the Bible, archaeology and history, the entire human race had become polytheistic. We have no record of anyone worshipping the God of the Bible, the God who created the heavens and the earth and the first human beings. The human race served other gods, but not the true God.
What happened when the human race became practical atheists? God intervened? What happened when the human race built a city and tower toward heaven? God intervened. What happened when the human race became polytheists and worshipped anything except God? God intervened.
