The reason why God confused the languages at the Tower of Babel was, because people, working together under one language, would ultimately destroy themselves... ultimately fight God so that they would bounce off His almightiness into destruction. God didn't want that. That wasn't why he made people in the first place.
Consider... why are we building rockets to go to the moon and other planets? When you consider how much trouble it is, we might not even be able to do it. But if we can, there isn't any place out there that we know of, that has what we need just to live like the earth does. In fact, we don't really know everything that we need in a planet just to live. So, why are we trying to go? What is the "itch" that people have that makes them want to go to the stars?
If we put as much work into making the earth more habitable as we are into the space program, we could make the earth support a hundred billion. And certainly God would help us do this if we wanted to follow His ways.
Personally, I think that the reason why we feel the thrill of going to space is because that is where Satan is from. And he placed some of that feeling into us by genetically manipulating the forbidden fruit that Adam and Eve ate. Satan is using us to get back into space. The fruit of the Tree if the Knowledge of Good and Evil was Satan's start point to use people to get back to the stars... where he was kicked out of in the war with Michael the Archangel. We are pawns of the Devil.
The Tower of Babel was a way the people of that time were trying to get to the stars.
