What was the average IQ of Neanderthals?

Neanderthals were originally a white subhuman inferior species that lived in Europe a very long time ago. And all of their people died out so none of them are alive anymore. They are technically not "human" but they were living in Europe and the humans were living in Africa and one theory is that the humans down in Africa came upstairs and slaughtered all of the Neanderthal people because the Neanderthals were too peaceful to fight back. Neanderthals buried their dead with flowers suggesting they were religious too. They also fucked human women and were able to produce children with them which is why most Europeans today have Neanderthal DNA in them. Only Europeans have this DNA in them.
