The pyramid of Giza has been a story for a while. This structure is the largest among the rest wonders among the world and the oldest one too. Looking into the depth of the theories there have been many theories that has outlined the existence of this very structure and accordingly there have been many explanations for the same. Some say that it was a consequence of alien invasion whereas some say that it was built for depicting the worlds end. But, actually all these theories are doing is that they are making it more difficult of the researchers and scientist to confirm, the true theory behind it.
The most enchanting theory sates that the pyramid was built by the aliens but, fortunately there is a proof for the role of ancient Egyptians in it. The pyramid blocks were hewn from the quarries by the use of the stone and copper tools. The granite used in this process was quarried by the use of dolerite. The blocks were then easily transported by the help of remote quarries using the barge. The wheels weren’t used that time so the sledge was dragged manually by beast burden. Though there are still questions of how these heavy stones were lifted, he alternative would have been the pathway that carries the sledges to the top and then this pathway would have been covered to.
Another theory states that the pyramid was carved out of a single giant limestone blocks that was carried up by the workers. Joseph Davidovits, Director of the Geopolymer Institute in St. Quentin, France, says that the pyramid was actually built by the use of mixture of limestone, clay, lime and water. Now for sure believing in later one is still justifiable but the former theory has some explanations that are very mush reasonable. So for this the first theory is accepted by many scientist and researchers.
