Social Studies - Pyramids and Conspiracies

In Social Studies we are learning about how Egyptians made pyramids. So far we have learned about how the Pyramids were actually built by paid labourers and not slaves. The paid workers also got the honour of being buried in the pyramids. We had to write a couple of paragraphs about something to do with the pyramids. I decided to look into two conspiracies people have about the pyramids. Although I personally do not believe in these conspiracies I thought it would be fun to look into why people believe them. Here are my paragraphs:

With today's technology, we would not be able to replicate the Pyramid of Giza. Due to technology being lost it would be nearly impossible to remake the pyramids, because of this some people believe that aliens built the pyramids instead. The pyramids are a huge structure and still cause scientist and archaeologist confusion when it comes to how Egyptians made them as they struggle to see how they successfully made dozens of pyramids to stand without falling, be symmetrical and how they got the heavy stone up the pyramid. Some people believe that ramps were used to carry the stones up the pyramids (there are actually traces of where the ramp used to be)  while others believe that aliens used their advanced technology to lift it and place it in the perfect position. People think this as the limestone used is very heavy and would be a struggle to pull to the top of a 138m structure. Other than getting the limestone up to pyramid it would have been hard to achieve a perfect position easily. The Pyramid of Giza is in a position where the corners of the pyramid face the northeast and north-west perfectly, it also is aligned with the magnetic north which would have been hard to complete on their own, because of this it is thought that the pyramid wad levitated above the ground to then be put in a perfect position. Although Egyptians may do this on their own, without some supernatural levitation, some people are not able to see that the Egyptians could've accomplished this as it would've been extremely difficult to align these perfectly. It is thought that the pyramids were built with technology far more advanced with what the Egyptians had access to, therefore aliens are suspected to be the creature that built them.

If you are unable to see how aliens constructed the pyramids then maybe the idea that someone travelled from the future to build it instead. Even though I don't fully understand this conspiracy I thought it was interesting and decided to write what I know about it. This conspiracy isn't is popular and isn't very known but it is backed up by Stephen Hawking so like it's not that insane or impossible to believe. I found out this conspiracy after doing a lot of research and I think that the first one to publicly state this conspiracy was Scarlett Moffat when was on a British tv show called 'Im a Celebrity'. Scarlett said "in order to travel back in time, we have to go faster than light. The speed of light is the same latitude point as the tip of the great pyramid. The speed of light is like 319 and then loads of numbers, it’s exactly the same latitude point as the tip of the Great Pyramid. So I think someone from the future realized we’d need the pyramids and went back in time and built them.” Although I don't quite understand this statement I think it basically suggests that the pyramids were discovered to relate to the speed of light and were found to be a crucial part to how time works or are discovered or something so someone timetraveled back to the past to build them. People believe this conspiracy because someone time traveling is easier to comprehend than aliens and someone from the future may end up with technology just as (or more) advanced than the technology aliens are thought to have. Personally, I think that it is more believable that someone from the future built the pyramids compared to aliens as I don't really think aliens are real and because time travel doesn't seem impossible in this world.
