@bigtom13 and @adsactly, This continuation is really appreciable and literally speaking whenever we talk about the first Humans then for sure it's an subject of deep research and deep exploration because we are searching for the pieces which we never witnessed. But the beauty of the research means, we can deep dive and we can create an outline of history through available evidence.

As you wrote, first humans came to the Mississippi valley about 12,000 years ago,that showcase what is the nature of the history and whenever we think about the time span of human beings and the generations of human beings covered gives the great essence for sure.

And i want say one thing that, in my opinion Ancient Beings were really technologically developed and today we see Satellite Images in digital form and there are historical facts where Ancient Cave Man drawn the art of pictures which decoded as same which we see today as satellite images, so it's telling that, we are thinking only we are advanced but it's not true in my opinion because, ancient beings were advanced and in my opinion one example is Pyramid Of Egypt which is super advanced in the aspect of mathematics and it's really matched with the star calculations too, that's something amazing stuff.

Keep up and keep explore the Historical subjects and hope that you will going to share more amazing writeups in future.

Wishing you an great day and stay blessed. 🙂
