Mark of Cain

I just thought of something. I started reading into Neanderthals, can't really remember what started it, but i might of figured out what happened to human culture. Neanderthals were absorbed by humans and the descendants of this union is where the Aryan's and the "Myth" of Cain came from (Ishmael). This would explain the aggressive behaviour, the "Mark" (Fair skin, freckles, Ishmael again) and where the Idea of Agriculture came from. Just remembered, was reading an article on new discovery of three different populations of Neanderthals (USAToday). Now, a flaw is believing that agriculture came from them, but not necessarily agriculture but the aggressive behaviour behind totalitarian agri. Another Idea i have a problem with or that should be reinterpreted, is that if Neanderthals being stupid or of lower intelligence, or of being docile or less aggressive than their homo sepiens counterparts.
The timeline would be:
Neanderthals and Sapiens appear (one did not follow the other, they co-existed)
They interbreed, Neanderthals are absorbed into Sapiens.
These descendants maintains physical and psychological characteristics.
They converge in Gobleki Tepe and organize the tribes there for constructing the Temple.
To sustain the large population that begins to gather, Agriculture revolution takes place.
Totalitarian agriculture develops and is maintained because through aggressive nature of Nsapiens.
Genesis Myth is Born (garden: Gobleki Tepe, Cain: Nsapiens)
The rest we're living now.

Now, all i need is to become and Paleo-archaeologist, geneticist, Religious scholar and several decades and I'm sure i can come up with a very convincing argument.

If anyone has any ideas would be welcome to hear them.
