I’m used to hearing that ancient Egyptians invented nearly everything: beer, paper, ink, sails, multi-dimensional Stargates. Now it seems they may have also invented concrete.
Of course Zahi disagrees. Or at least he will until he reveals it on his next National Geographic Explorer special.
They might have invented it, but islam destroyed all knowledge about it.
Congratulations on living in egypt for 1500 year at 2 kilometers of the evidence and not finding it.
