I like the Gnostic explanation that the being who created the material universe was a lesser deity of some sort (I think they call it evil but I’d probably go with chaotic or something). It made people to have intelligent-ish beings to interact with, and it put the Trees of “Knowledge of God & Evil” and “Life” in the Garden (for some reason) but didn’t want Adam & Eve to become knowledgeable & immortal.

In this telling, the “Serpent” is Jesus by which they mean the physical projection of the actual highest actually all powerful, all loving, etc etc god, and it wants to free A&E so it convinced them to eat the fruit.
