Let us just step back:  two hundred and fifty years ago, or so, the ships of England and Spain had drifted onto a whole new continent, as they saw it, from far north to a savagely cold south; pole to pole, as if there were such things. Millions of people already lived here, some of them still hunters and gatherers; some of them very wealthy, indeed!  Gold and silver stolen from the southern Americas funded Spanish and English dreams. There was land, lots of land, under starry skies above, rich land, and oil and coal and iron ore.  The whole western world learned how to build industries not on simple muscle power, but on steam and oil.  We farmed, too, of course.  All we needed was cheap labor--slave labor from Africa, mostly, so the ships came with slave labor.  Chinese labor built railroad beds where there had been rock cliffs. Europeans, long used to killing each other for good, religious reasons, brought their religious savagery with them. ...

We do not see things in enormous time-frames.  We human beings are fairly new at figuring things out for ourselves.  For instance, some  people today still think of the earth as a newly created thing, perhaps ten thousand years old.  Earth is actually about four-and-a-half billion years old.   That is to say, the earth is 450,000 times older than the Adam and Eve story, and the universe is three times older than that! I recall first hearing that continents were slowly drifting around the earth, and that there quite likely had been several times when the continents were squeezed together.  But people could stand on the edge of their own continents, and not see Africa or Asia getting closer.  It took at least fifty years to figure things out. We called our continent something special. But sure enough, there have been numerous times during several-billion year history of the earth, when supercontinents formed, and eventually drifted off. ...
