I always wonder how many times human civilizations rose and fell before our latest burst of growth and advancement during the climatological stability of the last 3,000 years.

People think I’m a bit crazy when I suggest that much of humanity’s history is probably buried under tons of water on the continental shelves.

I often wonder that myself. Sometimes I wonder if there were advanced human civilizations here on Earth that ended up being destroyed by natural or man-made catastrophies prior to our own.

It’s been discussed on FR on these types of threads before, but the ancient Veda texts from India describe things that sound very much like nuclear war. I’ve also read there are places over there where there is glass under the sand and it has residual radioactivity higher than the ambient terrain.
