Imagine a world without white people

Would Humanity be overall better off or worse off if white people never existed?

Do you think we would be living in a more peaceful world?

I think for sure we'd be living in a much more Primitive world by comparison as virtually all Inventions and Discoveries have been made by White People.

I think that the color of your skin has very little to do with your cultural and knowledge advancements. How can Africans and South Asians or Native Americans produce anything in recent history when they were enslaved by European imperialism for hundreds of years? Before that they all had very advanced cultures, much more advanced than most European ones.
