This is an very entertaining story, but a story is all it is, there is nothing based in science that can confirm anything about this topic. There is no scientific evidence linking the asteroid belt with the remains of FICTIONAL planet called tiamat or whatever, if all this happened millions of years ago, its all speculation unless you were there to see it all in person, which i highly doubt anyone reading this post is that old.

There is archeological proof that humans have been on this planet for WAY more years than a meager 6,000. The oldest humain remains found to date are 3 million years old and have been dubbed "lucy". Furthermore, the cylinder seals found in ancient sumerian ruins and the tablets themselves cannot BE deciphered, that language died out LONG before the pyramids in giza were even imagined. There is no way to determine what the tablets or cylinders say, the only way we even know a tiny bit about what the hieroglyphs of egypt say was the rosetta stone was discovered which helped translate ancient egyptian into greco-roman.

You can site scripture and pray to the gods and do a little dance and its not going to get you any closer to the truth than this one statement, without proof, no one really knows, dead languages are just that, dead languages. Also, if there were people from another world or planet or starship and they came here and made humans and settled here, where the hell are the remains of their technology? Im sorry but trying to tell me a pile of rubble and ruins without significant advances in technology located anywhere within is an alien starport or advanced civilzation is a load of malarky.

I"m not saying that humans are the only intelligent or sentient life in the universe, as a scientist it would be arrogant and irresponsible to presume such a thing, our galaxy alone is fillied with BILLIONS of stars, many to this day we still cannot see even with hubble or kepler, and of those billions of stars there are billions of planets in just our galaxy alone, and there are a billion more galaxies in the univers, there maybe trillions. Im sure there probably are other forms of life maybe even civilzations out there, the mathematics of probabilities favors a greater chance of intelligent life or advanced civilzations out there, than there being a chance of them not existing at all. Even IF there were other advanced civlizations, there not 100 or 200 or even 1000 years ahead of us, theyre a million or more years advanced than we are. We will never terraform mars, its too small and its gravity cant hold a heavy atmosphere, in our lifetimes we will never colonize our solar system, star trek isnt real folks, and if it was you'd be better off wrapping tin foil around your heads instead of trying to meditate to send thought projections into space at god knows what is out there, after all, if youre in the jungle is it wise to call out?

Facts are only facts if you can prove them, and without scientific/determineable proof all it is, is a story. Most of those legends of gods and deities had moral implications to them to teach people how to act properly before the invention of laws came about. Is there a god? i dont know, i cant speculate about what is and what isnt because i only believe what i can prove, but to actually believe this fantastic piece of fiction without any real proof at all beyond what was passed on for generations, until it became changed and fell into the realms of myths and tall tales, you'd have to be nuttier than squirrel turds.

If you have further interests into the possible realities of the future of the human race and where its going, i advise you to check out Dr. Michio Kaku's works.
