This is the book of the generations of Adam.
Genesis 5:1
Telescoping is taking an actual historical event and as it spreads out over time, the story changes--but some core elements are still present as well-in various ones- tidbits of different details.Take the story from the ancient Asiatic Indian Puranas and Brahmanas. A sreies of 10 Manu's descend from the gods at creation. The tenth Manu is the one where the global flood occurs. Did you get that-not just about a global flood--but the 10th manu?
