Not so much knowledge in history

Thats true. Like sad earlier by Cbvani germs and Smalpox surely decimetad the native Amercans.

About why they didn't make Iron weapons I heard of theories that clam it also had Geograpical reasons - since the american continent is somewhat divided by different climatical zones use of Animals and technologies could only spread at a slower rate if at all.(use of metals agriculture, keeping livestock and other Animals and writing didn't form in Europe but rather in the Middle east and later spread in Eurasia where it was perfected) Beside they believed obsidian to be effective enough so they didn't look for new Materials.

Tha fact that the natives weren't united against the "conquerers" also had an inpact - some sorcues mention that by the Time the Incas rebelled every Conquiztador was protected by 2-3 warriors from Native tribes allied to them.

Men have always looked for ways to better their technologies, thats why we went from the stone age, to bronze age, to iron age, etc. I believe the downfall of some of those civs is human sacrifice, as in the POWs were sacrificed, it turned a lot of subjugated people against them.

And it still doesnt explain the "American" cultures, there were no great cities there (there were probably about 300,000 in mixed tribes), but yet they never advanced, past the stone age. I do believe the bow was a superior weapon to early firearms, it could fire faster and farther, but the arrowheads were still stone.

Their primary melee weapon was the tomahawk with a stone head, if they had just advanced to the bronze age, things would have been different.
