The PBS science program Nova has an excellent three-part series that was first broadcast in 2015 on the history of the continent. They use nice special effects to bring vividly to life the very slow processes of geology and biology. Each episode lasts about 50 minutes.
The first one deals with the geologic history.
The second deals with the evolution of life.
The third deals with humans. I had thought that there were just two theories for how humans arrived on this continent. Either they came from the east and crossed the Bering Strait land bridge that was exposed during the last Ice Age when ocean levels receded. Or they came from the west by ships that hugged the North Atlantic coastlines. [Correction: I had misremembered. I recalled something about people coming to the Americas earlier from the west but that ‘earlier’ only meant before Columbus and not that they were the first inhabitants.] But this program says that the earliest human remains have been found on islands in the Pacific just off the west coast of the continent, indicating that they must have come from the east by boats. This was new to me and I need to look into it.
Whenever I see these programs, I am always impressed by the grandeur of the story being told and the dogged work of so many scientists who have been able to piece together the narrative of things that occurred long before there were any humans to observe them.
And that feeling is always followed by a sense of sadness that those who believe in a 6,000 year old Earth are missing out on that sense of wonder. Oh sure, maybe the belief that “God made everything” fills them with a different sense of wonder but that seems so shallow to me.
