Well, I have a history question that I can't figure out...can someone help me?

Question

At least by 15,000 Before Present the first humans arrived in the Americas. In a paragraph explain why most American History fails to address this.

Answer 1

Most of our history classes focus on our own society and advancement.  The bulk of American history is from the past three-hundred years.  You'll hear about some subjects a little before that- Roger Williams, the Salem Witch Trials, etc., but little more.

But anyway, the indigenous migrators of 15,000 years ago really did little to influence American History as we percieve it, as our American History is really an offshoot of European colonization, and not the descendants of those first arrivers.
