Black people invented everything

Interesting video that shows how many things came from black people. Althought I cant corroborate this things yet, I want to give some thoughts on how much of the science and development gets done. At the moment most of these breakthrough gets done through groups instead of only 1 or 2 people.

At the same time, is incredible the amount of documentation this video takes, and would be great to verify all this.

What do you think? You think these things can be verified?

At the same time, I think a lot of people will learn a lot from watching this video and whenever they have the patience to ratify the inventions.
