I have seen maps of Pangea before, maps depicting when the continents were all much closer. The one I was looking at recently was one depicting when the Sahel was lush and full of vegetation. Prior to seeing that, I was ignorant and had never known that region was not always a desert.
Been looking at maps like that since I was a child but didn't have the discernment to see that Mother nature always changes. Then, I realize that the people who were living in those places either died or had to migrate as the land took on a new face or went away totally.
In this way, I do think we are living in end times, but it is just life ending as we know it as Nature's face is radically changing again and we're the generation(s) around to witness it this time.
I think the maps will have drastic changes on them again in the next century, likely depicting major changes in the coastlines of some continents and maybe the disappearance of some islands we currently see.
I truly , 100 percent believe that the big change between caveman humanity which you are describing who had to accept planetary changes and migrate at nature's whim, and you or I today, is technology.
I see the maps staying exactly the same, but humanity finally tackling the weather itself the same way we tackled mass agriculture, cholera, malaria, polio , space travel, etc. Admittedly, I'm slightly biased due to my engineering background, but I truly believe geo engineering is the future. We have all the necessary tech to control weather patterns and we have had that tech since the 80s.
Much like climate change which our govts knew about in the 60s but did not take seriously until the mid 00s when things got bad, I see that same geoeningineering tech being put on the sidelines . The day that DC or Moscow or Shanghai floods, will be the day humanity blocks out the sun itself (through satellites at planetary legrange points) and starts active carbon capture factories.
Just like how ecologists and climatologists were frustrated with obvious changes being ignored for half a century; engineers and physicists are frustrated in 2023 about obvious and cheap solutions being ignored.
