The Tower of Babel is from the Book of Genesis, giving reason for the existence of different languages and cultures. Basically God saw people trying to build a staircase to heaven (the tower of babel) and then confounded their speech so they could no longer understand each other, ensuring the tower to heaven wasn't completed.
### Modern Use
This parable is still referred to when talking about things like [[Character Encoding]]s and straight-up language learning.
