What would the world be like is white people never existed?

You would not be typing on that thing you are typing on, no electricity to power it, you'd probably be dead by now for lack of medicines, medical techniques, medical research.

You would not have central heat / air, your food source would be tenuous. You would not fly, you would not drive, you would not have a trains to ride. No telephone.

Not much in the way of higher math, physics,

my fingers hurt from typing

I'm not that sure. I don't think so, really. I've seen some nuts here on Y!A say that whites do everything good. Here's a counterexample: US News published a special report on what life was like in the year 1000 AD (published at the new millenium). They said that at the time, China was at least 300 years more advanced than any other nation.

No Jesus, Moses, Mozart,Freud, etc

Just look at Africa. Grass huts and poverty.
