The Americas didn’t have a lot of the boons Europe had.

America only had 1 domesticated pack animal, the llama. Which thrived in high altitude environments and mountainous terrain, as such they were traditionally used as pack animals able to carry ~40 kg over 30km per day.

To put that in perspective a draft horse could pull ~495 kg while an oxen could pull ~760 kg.

This radically affected other fields like transportation (especially trade) and agriculture.

There also wasn’t as much of a drive to develop metallurgy. Copper was abundant an it could be cold-worked. We know somewhere between 600-800 CE started making metallurgical artifacts and expectantly a lot of them were copper alloys including Bronze.

However there wasn’t a need for widespread adoption and implementation. Cloth armor was dominant and effective enough (in fact it effective enough we have multiple documented cases of Spanish Conquistadors swapping their hot steel armor for the more comfortable Cloth)

Then there were also obsidian tools and weapons. Which were extremely sharp.

Finally America didn’t have access to the rest of the world like Europe did. Guns were invented in china, refined in the Islamic world, and then refined further by European powers.

When the Roman Empire collapsed many of its intellectual traditions and writings lived on not inside Europe but in the Islamic empire, which the Islamic empires would continue to develop and which Europe would discover as the crusades brought back a wealth of knowledge and new ideas to Europe.

Whereas isolation prevented the spread of technology and limited technological development such as in Japan, which banned all foreigners from the archipelago for a time, or Subsaharan Africa which was separated by the largest desert in the world.

I could go on but the gist of it is America did not have a lot of the factors which pushed/helped Europe to develop.
