That's not true. Rather, Egypt was essentially polytheist, to the exception of a brief episode of monotheism imposed by a ruler (Akenaton) who didn't last very long.
You believe Egypt is understood as you believe the Genome is understood.
Even ancient Judaism, which was derived from an Egyptian context and strongly influenced by Egyptian religion(s), was originally polytheist.
The migration of man, out of egypt we hear the words... go forth and populate the earth and the law was condensed and made transportable.
How did all this come about? Was it as we interpret things or is there some other explanation.
What does understanding require? Really?
We don't live in a flat world and as far as I can tell nothing is yet fixed so why should we yet give anything permanence.
This is this and that is that? Really?
What does it take to inquire about things? What is imagination? What is all this nonsense?
