It doesn't say that.
“The official science has been saying all along that the ice-cap which covers the Antarctic is million years old.
The Piri Reis map shows that the northern part of that continent has been mapped before the ice did cover it. That should make think it has been mapped million years ago, but that’s impossible since mankind did not exist at that time.”
The bad grammar was present in the original.
It goes on. Here’s a beaut: “Charles Hapggod, in 1953, wrote a book called “Earth’s shifting crust: a key to some basic problems of earth science”, where he made up a theory to explain how Antarctic had been ice-free until year 4000 BC. (visit the Bibliography )
The theory summing up is as follows:
The reason Antarctic was ice-free, and therefor much warmer, it is to be found in the fact that, at one time, its location wasn’t the south pole. It was located approximately 2000 miles further north. Hapgood says this “would have put it outside the Antarctic Circle in a temperate or cold temperate climate”.
Cogent and well-argued?
