Just a theory

[Fake Messiah]

I’ve always thought  that religion was first invented to explain what our early ancestors didn’t understand.

It seems that humans were inventing religions two times because human look on a world changed almost completely when they switched to agricultural society. So humans invented gods once when they were hunter gatherers looking out of caves and wondering about what they saw. What made the lightning flash? Where did the wind come from? Why would winter start soon and why would all the green things die? And then why did they all come back to life the next spring?
The wind is much stronger than the breath of any ordinary man and it had been blowing ever since man could remember. Therefore, the wind must be created by a tremendously huge and powerful man, one who never died. Such a superhuman being was a "god" or "demon."

But then as humans became agricultural gods took a turn to be about food. There needed to be like a mediator between the idea of life-force that comes down as food, feeds people and then people give back to the life-force and then it goes back again which were kings and ruling class.
The Bible used a tale of forbidden food to define all of human nature.
Mayas believed that maize was the flesh of the gods containing divine power, and at harvest time the gods were, in effect, sacrificing themselves to sustain humanity.
Aztecs belived The Earth Mother was nourished by human blood and the crops would only grow if she was given enough of it.
Incas also thought sacrifice was necessary to nourish the gods.
In China both gods and royal ancestors were offered grain, millet beer, animals and human sacrifices. etc
