Growing up, I always thought the people who built the tower were spiteful of god and wanted to reach the heavens to prove he wasn't all strong and whatever. But then I actually read it, and the only arrogant part of the people is that they just wanted to be famous lol. So just because of that, "the LORD said, "Look, they are one people, and they have all one language, and this is only the beginning of what they will do; nothing that they propose to do will now be impossible for them. 7 Come, let us go down and confuse their language there, so that they will not understand one another’s speech.""
TLDR: "These people have solidarity with each other, and with that, they can achieve anything they want. That is unacceptable. I will now make them hate each other for arbitrary and artificial reasons. I am good and love everyone, by the way."
I remember when I was a kid and decided to read the Bible. When I got to the Tower of Babel I just couldn't let it go how absurd it was that God would do that and none of my church leaders had any satisfying answers. They reference it in the film Metropolis, where the story is altered to just be about workers and bosses, it's a really good film.
