This is a fascinating website here: Ancient Patriarchs: https://ancientpatriarchs.wordpress.com/2018/02/27/wow/ In the youtube video it speaks of the preference of the LXX over the Masoretic for the geneologies in Genesis. It makes more sense. I am a Young Earth Creationist but have always doubted the 2350 date for the Flood put forth by many YEC folks. There was not enough time between the Flood and Babel. This website shows the Flood was probably more likely at least 3000 BC.
