Obviously not people

C'mon guys...

 The 3 pyramids of Giza were built in size and proportion to the 3 stars in Orion's belt. If the location of the stars is traced back over thousands of years, the time at which the belt is exactly aligned with the pyramids is in fact 10,500 BC.  

The pyramids were built in 10,500 BC- as well as the Sphinx- which had water wear from that era- which is well before the Egyptians.

  Other facts:

 If you take the perimeter of the pyramid and divide it by two times the height,  you get a number that is exactly equivalent to the number pi (3.14159...) up to the fifteenth digit.  

 If you take the line of longitude that the pyramid lies on and the latitude that the pyramid lies on, 31 degrees north by 31 degrees west, they are the two lines that cover the most combined land area in the world. In essence, the pyramid is the center of all of the land mass of the entire earth. 

The height of the pyramid (481 feet) is almost exactly 1/1,000,000,000 of the distance from the earth to the sun (480.6 billion feet)

The diagonals of the Pyramid also line up exactly with the delta of the Nile river:

Do people really believe that humans built the pyramids?
