Why Would God Hide?

[Tonus]

Speaking of Yahweh, according to the Bible he got so scared because of a tall tower and some iron chariots for some reason. Does this mean that said things were able to hurt him in one way or another? If so, he would have far worse things to be afraid of by now and a good reason to hide.

The story doesn't indicate his frame of mind, only his concern that the builders of the tower of Babel might achieve the fame they sought, and might become even more ambitious:

They said, “Come, let us build for ourselves a city, and a tower whose top will reach into heaven, and let us make for ourselves a name, otherwise we will be scattered abroad over the face of the whole earth.” The Lord came down to see the city and the tower which the sons of men had built. The Lord said, “Behold, they are one people, and they all have the same language. And this is what they began to do, and now nothing which they purpose to do will be impossible for them. Come, let Us go down and there confuse their language, so that they will not understand one another’s speech.”

It is, obviously, a fable meant to explain why there are so many different languages in the world, and/or why there are so many different nations scattered about the land. There are any number of interesting bits in the story, such as the notion that they might reach heaven by building a tower, or who god was referring to by "us," or what he meant when he said that nothing would be impossible for them.

At least, they are interesting in the context of someone believing it to be a true story, as opposed to the sort of continuity errors you might get in a day and age when writing things down wasn't as easy as tapping the surface of your smartphone.
