I'm talking about how the pyramids have recently been discovered to have near perfect bearings to North by multiple decimal places, calculated pi and e to something like 7 dps perfectly accurate and have made all their designs exactly the same to the same precision not even being able to place a piece of paper between 2 blocks. There are writings of somewhat celestial beings providing help and information nearby, and similar halfway across the world by other historic sites. Do historians give the idea of aliens or non human beings any credibility??
I would like to address the final question you pose in this post. No, historians and archaeologists do not give credibility to the idea of aliens building the majestic architectural structures located in non-white civilizations.
These ideas stem from the nineteenth century, when many western nations began looking to expand their empires. Egyptian history began reentering the European mindset during the campaigns of Napoleon Bonaparte in the first decade of the nineteenth century. You have books and series like the Description de l'Egypte originally published in 1809, which comprised of 37 volumes written by 160 scholars from the time capturing the attention of the European mindset. As these European empires begin exploring and conquering the nations of Africa, they find these incredible structures such as the pyramids, which run contrarian to the European mindset of Egyptians, for instance, being child-like or inferior. This threatened the Europeans' justifications of colonizing these nations. By the mid-nineteenth century you have the emergence of ideas like phrenology and the growth of the pseudo-scientific racism. So as the nineteenth century continued to progress, stories began popping up of aliens helping build the pyramids.
The same thing happened in the United States, at Cahokia Mounds, just across the Mississippi River from my home of St. Louis. In the 1820s-1840s, as St. Louis continued its expansion to become America's "Fourth City" and Anglo-Americans moved ever further west, examples such as the Mounds of the Mississippi culture from roughly a thousand years prior once again went against the grain of the beliefs of European-Americans within the United States that they were the sole heirs to the nation. Therefore, stories began spreading of even older and supposedly European civilizations building the mounds. This myth was even propagated by Andrew Jackson according to the source listed below.
In the end, these ideas became tools for colonizers to delegitimize the accomplishments of other cultures.
