Hello. I do not wish to debate, but merely point out a fact that the two necessary components for evolution, life coming from non-life
This is both right, and wrong.
It's right, in that you need life to exist for evolution (as in change in allele frequency in a population through inheritance) to occur.
It's wrong, in that evolution doesn't deal with abiogenesis (life from non-life) and the theory of evolution (ToE) only deals with life already existing.
It's immaterial to the ToE whether life formed via purely naturalistic means, was created by a deity or is the result of interference by a hyperintelligent shade of blue. All it does is explain what is observed in nature.
and a species becoming an entirely new species have never been observed.
That isn't correct. There are plenty of observed instances of speciation. Some of my favourites:
The evolution of a new British polyploid species of Mimulus
Cichilid fish speciation
The development of a new species of apple maggot, thanks to the introduction of new domesticated apple breeds
You can make the argument that we can't observe speciation because it takes millions of years for it to occur, but that does not make it science fact. Also Darwin's finches demonstrates genetic variability and is evidence towards adaptation not necessarily speciation. In conclusion speciation and abiogenesis (life coming from non-life) have not yet been or may never be observed and therefore should not be treated as science fact, but a belief.
Darwin's finches can - and have - been used as demonstration of speciation. Very recently in fact.
I agree that abiogensis has not been observed. But, it's unimportant entirely to the discussion. I disagree that speciation has not been observed - and I'll put forward the fact that biologists have observed dozens (at a minimum) of new speciation events occurring in the last ~100 years.
