Genesis Ch10-16: How did we get to where we are

God spread people from the city of Babel around the world. They all spoke the same language and had the same beliefs it seemed “And the whole earth was of one language, and of one speech. Genesis ch11 vs1” I think that the world would be very different if all the people in the world had the same language and culture. One new aspect could be that the world would be very united because since everyone had the same background and culture well problems would be very little but everyone would be more like the same like a prototype. It wouldn’t be as fun because everyone are very similar. With difference in the world there might be more problems but it is more fun, more open and different. Sometimes I wonder if other worlds do exist. If there would be other worlds how would they be? Could there be a person the same as me but with different personalities? Different physical attributes? I also sometimes think that if there is this other parallel world it would be good because due to this global warming and that the earth will no longer be livable in, it would be good because we can go and live in this other place which will be habitable.
