Here's an idea on the origin of languages......
Gen 11:1 Now the whole earth had one language and the same words.
Gen 11:2 And as people migrated from the east, they found a plain in the land of Shinar and settled there.
Gen 11:3 And they said to one another, "Come, let us make bricks, and burn them thoroughly." And they had brick for stone, and bitumen for mortar.
Gen 11:4 Then they said, "Come, let us build ourselves a city and a tower with its top in the heavens, and let us make a name for ourselves, lest we be dispersed over the face of the whole earth."
Gen 11:5 And the LORD came down to see the city and the tower, which the children of man had built.
Gen 11:6 And the LORD said, "Behold, they are one people, and they have all one language, and this is only the beginning of what they will do. And nothing that they propose to do will now be impossible for them.
Gen 11:7 Come, let us go down and there confuse their language, so that they may not understand one another's speech."
Gen 11:8 So the LORD dispersed them from there over the face of all the earth, and they left off building the city.
From Genesis, in the Holy Bible.
Not really. When did that supposedly happen?
