I thought plato described "orichalcum" as a copper/gold alloy. This alloy occurs naturally in only one place on earth, Peru. I've read reports that some anthropologists speculate that King Solomon's famous gold mines were at the headwaters of the Amazon River.
Egyptian cocaine/nicotine mummies are beginning to find a place in all the unknowns, huh? How did African bananas get to South America via the Pacific Ocean? (Are we beginning to connect the dots or just dreaming?)
What about the gigantic, ancient Olmec heads in South America that undoubtedly depict African ethnic features?
Ernest_at_the_Beach: No, I didn't, but someone should.
Names for the title of the bump list, anyone?
I hope they find Atlantis, but I suspect something else. There is a plan to find the extraterrestrial origins of life on earth --a hypothesis to be tested-- by drilling down to depths that would have been the surface a billion years ago. Most all of that is deeply buried so the present surface is relatively fresh all the time. Micrometeorite dust is still coming in at a rate that would bury everything a foot deep every million years, or something like that. I think they will eventually find completely lost cities and civilizations, very old and scattered all over the planet. I don't know how old they might be, but 50,000 years is not out of the question. Maybe more. I also suspect that technology 6000 years ago was more advanced than it was 1000 years ago. The first books I checked out of the library when I was old enough to go into the adult stacks were Velikovsky's, so I have probably been hopelessly spoiled as far as archaeology is concerned. I have seen the ruins at North Salem personally, they are very much out of place both in location and time, just like Stonehenge and the dolmens. We know people were sailing all over the planet 40,000 years ago, don't we?
An Atlantean Empire? Not likely.
Atlantis? Not likely.
Many prehistoric civilizations? Most likely.
