The tower of babble didn't not fall on top of the people working on it. It didn't fall at all. God only stop the group from working on it by changing their
languages so they couldn't finish the tower together. So, because the group couldn't speak to each other they all got into a group of people that could understand them and went their
separate ways. No one knows for sure what really happened to the group of people working on the tower or what happened to the tower itself. I strongly dought we will ever know!
