I loved this. I don't automatically accept every point made in the video, of course. Hancock makes a fascinating case for certain monuments being aligned to ancient (10,500 BC) star positions, even though the archeological evidence may say they are younger. Aren't temples almost ALWAYS built over older "sacred sites?" Christian churches over pagan temples, etc? Call it "Sacred Site Hijacking"
The video also makes me wonder what was lost when the sea level rose over 120 meters in the last 12,000 years. Wouldn't most of our current highly technological civilization be inundated by a rise of that magnitude? And how much of what remained wouldn't return to dust in a thousand years, much less 10,000?
Worth watching. As Dave Emory always says, "Food for thought and grounds for further research."
