send explorations into space if Earth was the size of the Sun.. Because we sent people into space decades ago when there was plenty of places on Earth that were unknown - we did it anyway to see what was in outer space.. the only true region left unexplored on Earth now are the deep oceans, although man is finally devising ways to go take a look - and they discover new types of life we had never seen before all the time..
So, in my opinion, man would till look to the skies and want to go check it out - even if the Earth was so large that we'd never finish discovering it all - just because certain people wanna go skyward, just like certain people, like me, wanna explore the depths of the oceans.. For us travel and exploration is vertical, not horizontal, if that makes sense..
Friendship is like peeing your pants.. Everybody can see it, but only you can feel the warmth..
