The Secret Gospel of John and the Book of Enoke is and such texts are mostly rip of from Sumerian sources btw.

The garden narrative traces back to ancient Sumer, along with the flood narrative. The origin of biblical claims and metaphysics is discoused in the context of its miljou.

For sources for Heracles, the garden of the Hesperides and dating, I recommend; Emma Stafford, Herakles. For antique sources I recommend the Hesiod´s Theogony, Apollonus´s Argonautica and Euripides´s Heracles.

For sources for the Epoch of Gilgamesh, there is free online versions, and even audio book versions.

For Atraharsis, there is also free online versions and audiobooks.

For gnostic influences and censorship in the bible, April DeConick is recommended. https://scholarship.rice.edu/bitstream/handle/1911/75007/hiding-Gospel-of-John.pdf?sequence=6&isAllowed=y

For the Egyptian origins of the biblical new testament I recommend "Christ in Egypt" by D.M. Murdock.

Frank O´Collins (and Michael Tsarion) have a lot of interesting thing to say about the origin of these religions. There is videos of him on Youtube, Rumble, Bitchute and Odysee of which I know.
