OP doesn't back down against the ivory tower elitists of /r/Askhistorians who only provided them with a "philosophical feel good answer" rather than truly addressing their questions about the underdeveloped Mississippi Valley natives.

I mean if I was an ancient civilization, I would definitely see this geographic area and think, “ I could thrive here “

So what were the differences in the need?

Can you provide an actual answer please?

This is just a philosophical feel good answer in my opinion

Why didn’t they develop Writing? Or systems of Centralized Power?

I’m generally curious as to why? Is it “bad” to ask the question? Let’s grow up and be mature

Am I not allowed to ask why these people didn’t create long term settlements after being there for hundreds of years?

Why did group A progress one way and Group B and C progress another? It’s simple as that. Why was ancient Egyptian’s practicing Mummification, medicine, and inventing paper?

It doesn’t have to be, “oh they’re just dumb, we’re white so we are SMART” I’m not saying that lol

Because all I’ve gathered so far through what you provided is, “the lifestyle didn’t require it”

“There wasn’t a need, so it didn’t get invented/used”

Wouldn’t Buffalo be considered draft animals? There was also Incredible farm land, diverse population of game animals.

I just see so many avenues for a huge population and culture of people. But, all they have is what now known as St. Louis?

If you think that is just "...a philosophical feel good answer...", as later in thy responses when you lol at implying that "Nobody is answering anything", rather than that many contributors have repeatedly, very patiently to my mind, endeavoured to answer whichever questions you pose might I suggest that no answer would genuinely satisfy you as, from thy attitude, you seem set on classifying those cultures as 'less civilised', than others, as you already know what you think of them.

Brother, you need to join a field crew, because you can move the goal posts like no one I’ve ever seen. Your original comment was asking about large settlements along the Mississippi, of which Cahokia is one. Quito is a city you may have heard of, as is Mexico City (the largest city in North America), both founded by Natives. You also might have heard of Los Angeles or Manhattan or Detroit or Chicago or San Antonio, or existing Native cities like Taos or Acoma or Santa Fe.
