(D)Evolution

Ever wondered how actually the great pyramids were built, or for that matter how a structure as simple as a stone henge was made, or even why they were made? Ever wondered if our antecedents (ones before 0 AD) could have been super intelligent and genius beings and could accomplish undertakings, which we didn't even dream, of a couple of centuries ago?

How do you think they made the pyramids, or for that matter the stone henge, which is even older? They didn't use gasoline or electricity (sources of power) to achieve something that human ability or might cannot possibly accomplish. They used existing forces like the sun, the wind and yes the gravitational force. But here I am talking about people living way before the time of stone henge and pyramids. Do you think they could travel between continents at that time (yeah on oceans of course)? Do you think they would have traveled the entire earth and would have been able to make an exact model of earth, all its land masses and the oceans, and yeah even its curvature? To be precise, could they be able to make a globe with super fine precision (something like half a degree error in latitudes and longitudes) without being able to look at earth from space? O hell did we even know of latitudes and longitudes 10-15 centuries ago? Did we (people not living on America & Antartica) even know that North America and Antartica existed on the face of earth at that time?
OK enough questions. But I guess this last one won't hurt :). Will you believe all this to be true if presented with some concrete evidence? Well you have no choice I suppose. So this is where The Piri Reis Map comes in. Piri Reis was a famous admiral of the Turkish fleet in the sixteenth century and he drew a map on a gazelle skin and wrote on it that he had gathered the data from many different source maps to make his own map. The surprising thing is that he had an almost perfectly detailed map of the Antartic coast line and the Atlantic side of the North American and South American coast lines and the northern African coast line. Antartica was not discovered until the next 300 years. And Columbus had discovered America only about a decade ago. Whats more surprising is the accuracy of the map (cartographers corrected some errors in the present maps after getting hold of Piri Reis Map). And whats baffling is that he claimed that the source maps were much much older. How did some one at that time accomplish such a feat? And what the hell did they want to go to Antartica for? Also the amazing thing is that they were able to record the curvature of the earth on the maps as well. So they already knew then that Earth was not flat (for disclosing which fact many great people were mocked in recent centuries).
So now what happened to this civilization? Where and how did they disappear suddenly? If they would have lived, would they have been much more technologically advanced then we are today? Of course yes, and I could only dream some of their works of arts. So what seems to have happened was this genius of a civilization was wiped out and what was left was a much dumber civilization which took hundreds of years of learning to be where we are today (Does that justify the heading now :)).
