Ok. So I have a compelling argument based on facts that Shows the existence of exterestreal life on earth. I believe Aliens created the great pyramids reasons being- 1.The height of the Pyramids apex is 5,812.98 inches and each side is 9,131 inches rom corner to corner. If the circumference of the pyramid is divided by twice it's height the result is 3.14159, which just happens to be Pi. Pi is demonstrated many times throughout the Pyramid, and yet we know that it wasn't discovered until later by the Greeks.. 2. As stated earlier each the Pyramids four sides are 9,131 inches for a total of 36,524 inches. 365.24 days just happens to be the exact length of the solar year. 3.The Great Pyramid is located at the exact center of the Earths' land mass. That is, its' East-West axis corresponds to the longest land parralel across the Earth, passing through Africa, Asia, and America. Similarly, the longest land Meridian, Asia, Africa, Europe, and Antarctica, also passes right through the Pyramid. The odds of the Pyramid being built in this exact spot are 1 in 3 billion. So it seems our Egyptian friends would have to know a mathematical concept they didn't have, the exact length of the year, the exact curvature of an Earth no one had yet mapped out accurately, and the exact center of the Earths' land-mass including continents they didn't know existed. Not only that they had to incorporate all this knowledge into construction of one monument. I'd also like to point out that the Pyramid would have collapsed under it's own weight if it were'nt for the fact that a small Granite mountan exists right under it. How did they know it was there? They certainly didn't have advanced mining equipment to check. Has anyone ever thought over these facts it interests me. UFO's have been in ancient history all over the world before there was communication between contenints. I BELIEVE THERE IS LIFE OUTSIDE OF EARTH. Any opinions on the theory?
