If I was one of the people who built the tower of Babel and my speech was changed to Spanish, I would find some other people who also spoke Spanish and they would choose me to pick where we would settle down. Of course this would take me a couple of days to figure out since I have to pick a place where all of these people can live and survive. I also have to pick a place where crops can grow, and a place with good game so that we would have fresh meat to eat with our crops.
I would choose to go to India because I think I could grow crops there and there is plenty of wild animals. They have really good spices to help with preserving our meat. It also doesn’t really get cold there so you can grow crops year around.
