Excellent question.
I think it could be for a variety of reasons. I think their overall prowess, impressive construction, and longevity plays a huge part.
There are three pyramids part of a cohesive design as opposed to just one pyramid by itself.
The presence of the Sphinx could also play a part, not many pyramids are accompanied by a structure like the Sphinx.
Egypt for a long time was the center of civilization, so naturally more attention will be on it.
Then you can get into all the metaphysical aspects like its alignment within the solar system, 20 ton blocks used in its construction coming from hundreds of miles away, etc.
Not to mention we still, in 2024, do not know how it was built.
Overall I think it's just the most impressive of all the pyramids on the planet so of course it gets the most shine. It's like when Kobe walks into the gym nobody is paying attention to JR Rider anymore lol
I'd be interested to hear your thoughts.
