Moreover, the construction of the Giza pyramids was solid enough to withstand the test of time due to the "attention to precision," (Guardian's Egypt). One of the core reasons for suggesting alien intervention in the construction of the pyramids is that it is difficult to imagine human beings from that long ago -- who had no electricity -- being capable of an engineering marvel as amazing as the pyramids. There are no existing architectural blueprints; plus, the only indication that a mason might have made a mark is in a lone inscription on one stone (Guardian's Egypt).

Moreover, recent evidence shows that slave labor was most likely not used in the construction of the pyramids ("Egypt: Secrets of an Ancient World"). Without slave labor or imported labor, a massive number of local workers would have been used and it is difficult to imagine organizing and coordinating a labor force of that size. The construction of the pyramids may have involved building ramps upon which the massive stones were more easily maneuvered into place. Yet even with ramps, stones that weigh up to eighty tones cannot be moved easily. Even if the Nile had been completely flooded, allowing for the ready transportation of stones from far-away quarries, no archaeologist can explain exactly how -- or why -- the pyramids were built.

It is possible, therefore, that aliens helped build the pyramids and may even have commissioned them. It is...

The average human being living in the time of the Old Kingdom in ancient Egypt could have been little more than an advanced primate and after mating with intelligent alien life forms, the human neocortex and frontal lobes might have thereafter began to flourish.
Sure, there is not one iota of evidence that would support the alien theory. No credible source from the records of any scholar, scientist, archaeologist, or historian testifies that aliens built the pyramids. The alien theory is a romantic one that captivates the minds and hearts of those who cannot possibly fathom human beings four thousand years ago being capable of the engineering feat still observable today in Giza. Without any proof to the contrary, aliens could have build the pyramids.
