Fringe beliefs - Do you have any?

[Arthur Dent]

the Egyptian pyramids, Easter Island heads, Atlantis, Olmec negroid head carvings, Stonehenge, and other ancient wonders are over 12,000 years old. The architecture and placement coincides with the star patterns at that day, like the pyramids of Egypt line up with Orion's belt in the sky in the year 10,500 BC and similarly the temple of Angkor in Cambodia lines up with Draco, the constellation of a dragon in the sky above, coincidentally in the year 10,500 BC. There's a few others existing today that also match up with constellations....
(I believe that there was an ancient advanced civilization that imparted its knowledge by traveling to lesser advanced cultures. That would explain all of the similarities in the ancient world)

Show me proof against any of this...you can't carbon date rock.

You can't carbon date it, but a geologist did an errosion survey on the great pyramid and the sphinx. His findings say they're both a lot older than egyptologists say.

I've heard a theory that there were several human civilizations between the period when homosapiens first evolved and the beginning of recorded history. They were periodically wiped out by natural disasters such as the ice age. Basicly, a civilization would rise, spread, and develope only to be knocked back down to primitive wondering tribes by a cataclysm with all records lost. We are the first civilization to make it to the point of an industrial revolution. All the others stopped somewhere around the bronze age. Atlantis may have been an island nation that survived a cataclysm in tacked while everyone else had to rebuild. Then they were wiped out by a volcano (at least according to Plato).
