If the ancients were able to make nuclear bombs than they most certainly would have been able to make plastic and being that plastic last forever, where are the plastics artifacts?
If Obama drives to world into a Mad Max scenario and/or the ice age comes back, 100000 years from now, some future archaeologist will still find my Styrofoam clam shell that my Big Mac came in back in 1975.
Same with Aluminum, up until modern smeltering techniques 75 years ago, Aluminum was rarer than gold. Where are the Aluminum artifacts?
That’s a good point, the ancients on stargate atlantis left all kinds of cool stuff laying around. hehe
With that said, Graham Hancock and others hold to a theory that mankind 30 to 40 thousand years ago had an advances stone age civilization that was drowned when the ice age melted since the cities were on the now submerged coast and the survivors of the great melt were the more primitive inland dwellers who remember this civilization as Atlantis.
Also, in one of my obscure readings I do recall an episode where in the Roman empire a goblet that had aluminum like qualities was created but it was a one off product.
Not too many people know the Washington Monument is capped with aluminium. When it was built, aluminium was the most costly metal.
Fred and Barney were environmentalists. They recycled EVERYTHING! Truly obsessive-compulsives, and blindingly disfunctional because of it. Unfortunately, they spent so much time cleaning up, the literally starved to death. True, it was an evolutionary dead end, but it left the earth pristine for us. Now, we’re not nearly as neat, but we have survived, and continue to increase our population base.
It just goes to show, if you’re kind of sloppy, you’ll live a lot longer, and your species is far more likely to survive.
