I think there is a deep link between physical geographical features of the planet or to the atmosphere or the ocean and the opportunities or challenges that's given people through the ages. Even if you re-round history back to 100,000 BC 10,000 BC those physical features would be the same they would have a similar driver or influence on the subsequent development of nomadic societies or settled civilizations. The pattern of winds around the world driven by atmospheric circulation and dynamics they would be exactly the same so you would be able to have trade routes in long similar lines simply because of the physics of the atmosphere. So I'm fairly confident about predictions about how that would affect the human story but you can't start
