Brains of the same batch

When God first decided to create humanity,
He created all the brains in row.
Thousands, millions, billions of them,
Each perfectly timed for its life on Earth.

Each had a different personality,
A unique outlook on life,
Different opinions on different subjects,
Different strengths, different flaws.

God pondered when he was done...
In the end he felt something was wrong,
If all the people were different,
And each opinion unique,
Then the world will always,
Always be plunged in controversy.

And so he categorised them all,
And he added cross-reference tags,
He tweaked a little date here and a opinion there,
And finally the batches were set.
Each batch was sent to Earth,
Scattered to the four corners.
And slowly, excruciatingly,
Some of the brains found each other,
Just like you and me my friend.
