You don’t understand the term “stone age”.
Gunpowder did not “bring down” Constantinople. The Ottoman’s canons were ineffective, and their mining operations were thwarted. Constantinople fell because the Ottoman’s were able to get their ships into the Golden Horm by rolling them over the land on greased logs and because the Ottomans had overwhelming numerical superiority.
Marie Curie did not discover Radium. Her husband AND she were credited with it. Pierre probably did most of the laboratory work because he died quite early as a result of exposure to radioactivity. Her later work isolating metalic Radium was done with Debierne.
Your post is so typical of the intellectually lazy on FR who will absorb whatever pablum is fed them on the “Hostory Channel” and in popular press.
If you wanted to argue that Egypt was more advanced, certainly they were - they were the most advanced stone age culture; but they were stone age until they got introduced to bronze weapons by the Hyksos invaders.
Can a stone age culture support a massive population and make huge monuments out of stone? Sure they can, and they did, in Egypt and in the Americas. Your infantile argument might have gone better if you made it about staple crops rather than chased after the red herring of “stone age”.
I don’t watch TV, so you had better try to grind your obvious ignorant (stone) axe elsewhere.
No bronze weapons = not yet bronze age.

“The number of the Ottomans was fifty, perhaps one hundred, times superior to that of the Christians, the double walls were reduced by the cannons to a heap of ruins, and at last one point was found which the besiegers could penetrate. Hassan, the Janissary, of gigantic stature and strength, ascended the outward fortification. The walls and towers were instantly covered with a swarm of Turks, and the Greeks, now driven from the vantage ground, were overwhelmed by increasing multitudes.”

I repeat....
the double walls were reduced by the cannons to a heap of ruins.
Radium was successfully isolated by Marie Curie in 1910.
Does her husband deserve some posthumous credit? Certainly. But she was the lead researcher in the discovery and isolation of radium and for shorthand it is certainly correct to say ‘when Marie Curie discovered radium’.
Any other nitpicks to go along with your troll axe grinding?
