If Europeans never colonized in the Americas, how do you think America would be today?

Well, eventually, they would have been colonized by someone else, possibly the Chinese or Russians.

But, if you are asking how the American Indian culture would have fared without any outside cultural influences, I would guess that eventually they would have advanced through the same cultural stages that the Europeans went through during the first two thousand years CE.

And, I believe that their formal development of religious tenets would have closely followed the religious evolution that occurred in Europe.

In other words, a unitary creator of the universe would have been eventually manifested by the culture elders and accepted by a majority of the inhabitants.

But, these conjectures are only inadvertent musings.

it would be similar to the parts of the world not touched by white man. pristine,clean,vernal,beautiful. the natives have a philosophy that is unique and have been tarnished by colonizers. progress is measured by westernization,christianization, consumerism. other forms of development are considered low/unworthy. if u visit the natural parts of america - isnt it beautiful. so it would have been so. natives are spiritual, respect nature and it would have been a more "advanced" civilization.

alas -...
