"No formation of new species was ever observed in human history - face it"

Uh ... yes, they have. Face that you don't know what you're talking about on so many different levels.

First, we don't have to observe a thing DIRECTLY to know it for a fact. ERVs and atavisms are strong evidence.

Second, yes, we have observed speciation in the human lifespan:
Nylonase digesting bacteria.
The existence of ring species.
