also as for egypt, essentially the people that were having a grand ol time hanging out in the quite habitable sahara fishing, hunting, doing a lil early agriculture in what was apparently a pretty cool savanna (you can find cave art of animals like giraffes in libya and other places at times you definitely wouldn't have been able to transport one across a friggin desert) - they all had to drastically change how they were living: population went for a shit, people either turned to a more nomadic existence (like out west), to oasis-type groundwatery places, or to the nile nile turned out to be a pretty good deal
