An example of an Egyptian diorite vase : http://www.egyptianmuseum.gov.eg/details.asp?which2=595 (the vase on the left of the image) Diorite is an extremely hard material similar to granite. How the **** did they make such beautiful vases out of such material? According to several websites, bones have been found of humans that would have been about 8 foot. As it is practically impossible to find info about this from regular scientific sources, I'm not aware of the credibility of these statements. The head could be carved out at 2500 BC, but not the body. The body is much older than the head, and that can be deducted from the severe erosion caused by rain (!) as I said, and by the restoration works that were done thousands of years ago. So have I. I still wonder whether it is as accurate as some claim it is, or not... The Maya calendar seems to have been the center of their civilisation. Why? And why did such a seemingly advanced people get extinct because of draught? My main interests just switch subjects every now and then But I've been way into all this, 5 years ago. First of all, what did Plato really know? And how much of his story should be taken literally and how much should be read symbolically? Second, there is a theory that can explain what happened 12000 years ago, and what will happen in the future too. There's a theory called "Earth Crust Displacement theory". It predates plate tectonics theory, and has been rejected ever since plate tectonics became school book material. However, some people suggest that earth crust displacement and plate tectonics don't exclude each other, and that both are real. About the Earth Crust Displacement theory : http://www.lauralee.com/rflemath/ecd.htm For Antarctica to be the lost continent, earth crust displacement should happen in a very short time. If this does take place, one may ask what's the cause? That's something Hapgood (the one who came up with this theory) and Einstein already were discussing about a few decades ago.
