Pyramids, are more advanced than skyscrapers Jovaro.
The exact positioning of a pryamid against the sun(26.5 degrees) so that if te pyramid was transparent, it would act as a prism.
The contruction of the pathways and chambers have all precise lengths used for calculation or based on calculation.
There are shafts there aligned on stars that were on that position during that time.
The whole construction method and building is way more advanced than a skyscraper.
A skyscraper is merely a repetitive construct with a balancer in the top. Not very difficult. They didn't build it couse they didn't need it.
The egyptians also used electricity to electroplate their swords with gold.
And why would they have batteries if they didn't know how to use it?
