The pyramids are located in the city of Cairo which is capital of Egypt has been always been subject of interest and research for historians and scientists. Today with their historical facts and features now these pyramids are considered to have built over a total time 20 years. Going through the pyramids structure shows that these structures were really to that of those belonging to those who were not possible to be built by simple construction. Even we compare these to modern construction practices then too it is not possible for anyone to construct pyramids of such kind. However how these pyramids came into existence is a question of prevailing assumptions and hypothesis one of which is aliens built the pyramids theory.

By observing minutely we see that each pyramid is a huge structure in size and these are made of a solid rocks. A single pyramid is actually a cluster of small stones. Weight of each stone varies from a single tone to as large as more than twenty tones. Whole of the great pyramid as a whole appears to be constructed of more than 100000 rock stones. Going through its process of construction and built up scientist observe it was not an easy task for someone who built these pyramids. As for their construction it is believe by any these were built by Egyptians. Many believe that a large rocky structure of more than twenty tones was pulled at by them and this was placed by them completely at a height of more than hundreds of feet.

However with the large sizes and structure it is concluded by many that pyramids were built by aliens. In logic they say that it was not possible form common Egyptians have built such pyramids as at that there was no any machines available neither they had other adequate resources. In this respect it is said Tep Zepi which is called “First Time” by many that Sky gods came down on earth and he elevated earth of mud and water. Then they flew through these elevated structures thus providing structure with further expansion. This further strengthens aliens built the pyramids theory. Many scientist deduce that Egyptian at the time of construction of pyramids there was no wheels known or invented but there are huge wheel weighing upto the more than 2 tons each.
