Does any degree of freemasonry proves Nadha Brahman ? Is there any proof that Egyptian civilisation paved the way for freemasonry ?

No degree or rite in the recorded works mentions or proves Nadha Brahma.

Regarding Egyptian civilization, traditional Masonic speculation frequently framed Egypt as the cradle of symbolic instruction 1. Early Masonic historians held that the Egyptian Mysteries communicated sacred truths through allegories and symbols, which were subsequently carried into Hebrew tradition by Moses 1 and into Europe through Pythagoras and the classical Greek and Roman Mysteries 13. In the Scottish Rite, notably in the Twenty-fifth Degree, and in the Royal Arch, elements of Mosaic symbolism—which shared ritualistic analogies with Egyptian forms—are preserved in the traditional degrees 1.

These historical claims do not, however, amount to documented proof of a direct lineage. Historical writers often relied on speculative hypotheses and contemporary commentators rather than independent research 2. The traditional legends linking modern initiation to ancient rites are recognized within Masonic scholarship as symbolic parables designed to teach moral and philosophical lessons, rather than authenticated historical accounts of physical descent 1.
