Before I get into that, has anybody watched the "Life After People" series on History channel. It shows how the world would exist after people, and only if people, for whatever reason, no longer existed. It shows in time lapsed animation how buildings would be enveloped in greenery. Or how they won't last more than 300 years without humans to do maintenance.
I've always said, who's to know we haven't developed largely at some point in time and then it all just disappeared. I mostly thought about this after Sept 11th, when those buildings came crashing down, the equipment etc., like phones, computers and desks, were just obliterated. Nothing left.
Then I watched the Life After People series. It states almost nothing man-made will survive more than 300 years, except some carving in a large exposed granite mountain in Georgia, called Stone Mountain, which has a carving of horse riding famous people of our early years here, with Jefferson Davis, Jackson and Lee. It will last, pretty much, forever. Then I thought, when we are all gone, future intelligent life finds it, they'll think, we thought those people were Gods.
Yeah, yeah, I know, the pyramids, and some other things have been hanging around for longer, but that's because we have humans to do the upkeep. Or they were made out of an indestructible material.
Anyway, I'm rambling, back to the point. This came out today about "Ida" an early ancestor of ours from 47 million years ago. She was found at the bottom of a shale pit in Germany. What seems remarkable to me, are the bones very similar to our own:
"Opposable big toes and nails rather than claws confirm that the fossil is a primate, and the presence of a talus bone in the foot links Ida directly to humans."
So that defuncts my idea of intelligent humans having modern conveniences a millenia ago, because, well, hello, we hadn't evolved yet. But it does destroy creationism, yet again, kind of like
Lucy did. But we people of reason know, religious groups just put there fingers in their ears and go "lalalalalalalalalala".
It takes a millenium to evolve.
