I came across this pages which talks about binary and the Egyptians. https://www.innerx.net/personal/tsmith/eghier.html

It's interesting.

All the best

There is a remark on that page:

"Early Egyptian Hieroglyphic mathematics used
"decimal Description, as we do now, and
"binary calculation, as do our computers,"

which is a little far fetched as the Egyptians did not have a positional system. I believe in Dantzig's "Numbers" he mentions an australian aborigine tribe who know to count to 6: 1, 2, 1-2, 2-2, 1-2-2, 2-2-2, many.

But the page and the links it provides are indeed interesting.

Thank you again,
