The fact that this ancient map could have been made with some sort of arial technology is quite a thought, isn’t it? Even if this isn’t an option, who had the technology to undertake such an accurate geographical survey in Antarctica a couple million years ago? How would they have known to detail the map as if it were taken from above, with knowledge about the earth’s shape?
It remains a mystery how the Sumerians, Mayans, and others were aware of bodies in space that are impossible to detect without modern technology, and were able to make calculations based on that awareness. This map is another example of just such a mystery, and suggests that the existence of some sort of ancient advanced civilization, with all the tools (or possibly more) of modern day civilization, is indeed plausible.
For more detailed information regarding this truly fascinating map, I suggest you check out source # 1 for starters.
I’d also like to mention that this map is part of a very large body of evidence suggesting that extremely intelligent, very advanced ancient civilizations once roamed the Earth.
