Earth is 4.5 billion years old. Our brains can’t grasp all the journeys of all humankind and their movements since the day we were created. The same goes for all the movements and migrations of other beings. And for sure, our brains have never been designed to think in the way most of us believe. Otherwise, we may say that the survival instinct is a product of superiority for the continuation of the human race.
Unfortunately, many things have been ignored in our huge space so far. We are just learning from historical stories through simulation or writing. But one clear thing is that the human race moves.
