The other day I realized that religions have changed over history, the earliest forms of religion were animalistic, in tribes, because people were mostly hunters and gatherers at that point.
Later, as people became farmers, their religion had multiple gods based on the seasons, the sun, the moon, mother earth. Then also the gods became more abstract, for example the greek mythology of Zeus and the pantheon of gods.
Then the religions of multiple gods were replaced by religions of only 1 god, such as in christianity and islam and heck, perhaps buddhism.
Now there are more and more people that adhere to a religion of 0 gods. Or no religion at all.
The apex of the evolution of religion seems to be non-religion.
