I'd love to review some parts of your writing.
The fact that all people are equal from birth is untrue. We are all very different from each other. We have different height, weight, skin color, brain structure. And it also happens that some parts of the brain have one person, but the other does not. This is a real scientific fact. And such people see the world in completely different ways.
What do you mean by "some parts of the brain have one person, but the other does not"? I can't understand it well.
At us from a birth the brain is arranged absolutely differently, than at them. Therefore, we will never understand them, and they will never understand us.
This sentence has grammatical errors and
hard-to-understand message IMHO. I think it should be like this (I'm not a native too, so this might be wrong as well):
Since birth, we have different brain structures. That's why it is impossible for us to understand them and vice versa.
Btw this is my first time knowing that someone here wanted to write a book. This is cool.
