How long have Native Americans inhabited the Americas?

Thank you, George, for this question. This is something I’ve been interested in for many years now.

According to this most recent article that I read on the subject, dated February of 2022, it looks like Native Americans began migrating from Asia around 36,000 years ago. I may expand on this answer later, but I will include the link to the article here.
