Tower of Bible and creation of languages

[Jesster]

So, what is the theists explanation of languages like French, Italian, Spanish?
God created more languages to increase the confusion?
After the supposed birth and crucifixion of Jesus Christ, God was still afraid that people will build the tower of Babel?

And why are there many programming languages? Is to make sure machines will not build their tower of Babel?

I'm certainly not a theist, but I can answer for one that I live with. My boyfriend, who is Christian, writes off silly stories like the Tower of Babel as fantastical fables that never happened, but had cultural value at some point in history. Even though he believes the core ideas in the bible, he accepts that a lot of extra bullshit was inserted by man as well. He's at least capable of tossing out the craziest of claims, so I can work with that. Fundamental biblical literalists make me cringe.

I'm not here to defend his point of view, so please don't ask for more detail on that one.
