Am I correct in assuming that most pagan beliefs come from Greek, Norse or Egyptian origin…?

When the Apostle Paul arrived in Greece he found many statues to gods. This is what he said:

“While passing along and carefully observing your objects of veneration, I found even an altar on which had been inscribed ‘To an Unknown God.’ Therefore, what you are unknowingly worshiping, this I am declaring to you. The God who made the world and all the things in it, being, as he is, Lord of heaven and earth, does not dwell in handmade temples nor is he served by human hands as if he needed anything, because he himself gives to all people life and breath and all things.”

God has set a day on which he purposes to judge the inhabited earth in righteousness by a man whom he has appointed, and he has provided a guarantee to all men by resurrecting him from the dead.”

– Acts 17:23-25,31
