You may believe that 'evolution resulted in sapient and sentient species' as a philosophical position but it is scientifically impossible to claim that it is a fact. Real scientists know that and would never make that claim.
Starting with the fact that I'm a real scientist, and I did make that claim, as I believe most real scientists that I know would also claim, that rather shows your last statement was disproved before you even typed it.
You may choose to believe that sapient and sentient species do not exist. I, however, believe otherwise. I take their apparent existence as being sufficient proof that they do indeed exist. As I've said, I really don't get into all of that existentialist nonsense aka philosophy.
