> I'm positively certain that in all of your examples people have pushed into new areas because of food, to find new land to live on, to find riches, to find the promised land or other mythological reasons First of all, you can’t be positively certain of those. We don’t have access to the reasoning of why the Vikings decided to cross the Artic to America, or Polynesians crossing the Pacific. Second of all, let’s say they did go to look for food. Are you sure they ran out of land to grow food, or forest for hunting that they had to look for new land? The answer is quite resounding no. Likewise, we don’t have to exhaust all of the resource on Earth before exploring other planets. Finally, what were those mythological reasons you listed there, if not the desire of human being to explore?

>>Are you sure they ran out of land to grow food, or forest for hunting that they had to look for new land? The answer is quite resounding no. The answer is an absolute and resounding yes, because that's exactly what hunter gatherers do - they move with the herds and where the food is. This isn't just an educated guess, we know this because there are still hunter tribes on Earth right now which do exactly this. >>Finally, what were those mythological reasons you listed there, if not the desire of human being to explore? We have historical records of entire tribes moving purely due to religious reasons, either believing that land somewhere else is sacred, or that the land they are on currently is condemned. If you think your deity lives over the horizon, then you get on your boat and go in that direction. Yes ultimately it's a desire to explore, but it's not just because it's "cool".
