What are the gods that humans worship?

[Sirius]

One of my favourite books is “The Source “ by James A. Michener.

It is fiction, but it gives an interesting perspective of how people began to worship gods. I have read it numerous times and the edition I have now is all taped together.

What is the tldr of how it began?  Interesting that there is a notion of a beginning of worship, it's actively happening, new religions pop up all the time and it's part of being human.  It's also very real to the people involved.
