As a christian, how did you handle the problems with the Tower of Babel?

[Brakeman]

So said god as told to DRICH. We call this SPAG. It means "self projection as god."

Let me correct your statement:
So God told DRICH. (Through the bible) We call this READING, What Is On Page without Adding Commentary.

Nope..
If anything, God told a bronze age goat herder who told another herder who could write, who then passed it one to another who copied that one before that original was lost, repeat Ad nauseam, until after several translations later, DRICH reads the script but doesn't directly interpret it in the common vernacular, but instead twists it's meaning more than silly putty to make it say what he wants it to say.

If a bunch of kids were trying to build a tower to reach up onto your roof, and you did something to scuttle their plans by splitting them up and then said that " I had to split these kids apart because together they can accomplish anything they set their sight to", then it is obvious to any non brain dead member of the human race that you were referring to the kids being able to have reached their original objective.

Ah, no. "Accomplishing anything in their sight" refers to far larger and more ambishious projects than a tower that could not exceed 10,000 ft.
Any "projects" that go outside the plan of salvation God has gets 'corrected.' Why do you think God had Israel destroy so many different people?

You have no special insight on what this refers to beyond it's direct reading. You are just SPAG'ing.
God had israel destroy people because the con-men prophets had no idea how to increase vegetable crops or maintain sustainable animal husbandry. They had to invade because they were too stupid and could only acquire sustenance for growth by animalistic killing of neighboring clans.

Why does god use the plural form here? why does he say "Come, let us go down?"

God the Father, God the Son God the Holy Spirit, or any combination of the three. All three or Combination meaning more than one hence the plural form.

So they talk to each other do they? What could one omniscient being tell another that isn't useless dunder-headery?

I wasn't aware that there was a set speed for mankind's development. Do you have any reference for this

Yes!
Genesis 11: 1-9

EW! Using a verse to refer to itself is using perfect circular reasoning. Not a single dent on that ring..
