Blowing off genetic studies in order for one to play "mix-n-match" isn't a valid means of finding answers IMO. What genetics has shown us, to a large degree, is what haplogroups were in which areas at particular times and where they originated from. None of which remotely validates the "mix-n-match" approach I've seen here in various discussions.
I'm not a linguist so can't answer your first question, but the second one is predicated on the belief that Hebrews were in Egypt (THE EXODUS). At the risk of being repetitious, there was no Exodus.
About Gobekli Tepe, I was reading a National Geographic article last night and realised that inside the circular structures which T shaped large pillars sat around the walls, also were 2 larger T shaped pillars, holding up the ? roof, if they had one, or sky..
2 large T shaped pillars, sounded like a very early version of the Pillars of Heracles or an Atlas concept - the rocks do actually look like priests, they have arms engraved on them and hands and loincloths, on a couple of the large T shaped pillars, 2 of them, in the middle of the circle.
