You have yet to explain how the Egyptians got this number (which would have been amazingly hard to write, by the way... because you have to start out by writing 311 of the symbols for 1 million (https://mathshistory.st-andrews.ac.uk/HistTopics/Egyptian_numerals/) -- and that Hindu cosmology was not defined until around 1000 BC (https://en.wikipedia.org/wiki/Brahma#Vedic_literature) which would be some 1800 years after the Great Pyramid was constructed.

He suggested that India did something similar to what Egypt did and that the Hindu ideas came from metrics important to their religion.

(his quote: * The employment of square measure, which appears to furnish the best solution of the Pyramid design, is singularly parallel to the use of square measure mentioned in the "Sulvasutras;" from those writings it appears that Hindu geometry in its origin sprung from the religious ideas of the building of altars, differing in form but equal in area. (See Prof.Thibaut in the Second "International Congress of Orientalists.") p 221)

How do you propose that they measured that diagonal? Given that the GP base is not exactly a perfect square, what is your evidence for them being able to do a large construction project and measuring the sides to within less than half an inch?
