Fanfiction/Please permit me to make wild allegations, I was also looking at this yesterday and wondered: is it the apple of knowledge of sexual reproduction? (I know the book says good and evil, I get it)

The other tree was the fruit of eternal life. They did not consume this fruit.

So, as for the story, humans could neither sexually reproduce nor live forever/a long time prior to eating the fruit of the knowledge of sexual reproduction. Life and death. Good and evil.

They ate it, wanted to have sex with each other and were ashamed and covered themselves to avoid sexual arousal.

The free will they received was the ability to sexually reproduce.

In the story, angels cannot sexually reproduce with each other?, but seemingly live forever/a long time, and angels supposedly did get very excited that they could now sexually reproduce with humans: nephelim. Hybrids.

Two different technology trees: humans with sexual reproduction and limited lifespan and angels with longevity/eternal life/angel powers.

This gave the world a third (unintended?) hybrid nephelim class and this upset the balance of power on earth/the creation.

The chaos that ensued inspired yahweh to flood his creation and try again?

Wild shit! For me these are the chaotic and confused retelling of a story of extraterrestrial influence on the development of the human species.

This particular chapter is focused on origins and bloodlines of humanity so it makes sense to me in that way 🙃

Thank you for your time.
