passing from history gradually over ~1500 years from 5,000 YA to 2,500 YA.
Subtraction doesn't seem to be a strong point here.
Anyway, moving along, I kinda like the "kinda cool" option of "sailing the stars" after inventing space vehicles.
Any idea of just how fast these things could travel at?
Also, I'm becoming intrigued with what sort of supplies would have been on board. Do gods eat or drink or even breathe air, after they become immortal?
And, how in Dickens, did they know where to go? Do you know where they might have gone?
Some say that the gods actually came here! I think from the Pleiades. They're reasonably close to Earth.
Maybe the Annunaki were Pleiadians on holiday or something. Some of those ancient clay tablets from Babylonia/Sumeria show a seven star system. I've seen them in the Louvre.
