Jovaro:
You done any research on the Great Pyramid located in Giza in Egypt?
The value of Pi 3.14 etc Can be found in the structure and all sorts. Its supposed to have lots of Mathematics behind it. Aliens didn't build it by the way, People built it.
People were ALOT brainier in the olden days. Besides ... they used to have good food too like Raw milk and Raw honey, for one ... Raw honey is not sold in ordinary shops anymore because the government know of the benefits so they put refined honey instead, and also Raw milk is made illegal because of it's amazing benefits, government dont want anybody to have the benefits of it. Research more on this.
Anyway the 2nd Law of Thermo-dynamics will tell you thinks degrade, even Humans.
I will post some archeological research/info later on to show people were very clever before. Thanks
