Moving the goalpost? No, just "proving" that evolution - or, how it works without HUGE issues, isn't even close to being proven.
Everything you've argued is untrue and comes from a position of extreme lack of familiarity with the subject. Seriously google for 10 minutes and you'd have tons of examples of speciation.

And, yet, you keep saying it is.
With reason, we've documented exactly what you are saying can't happen.

Therefore, why can't creation or at least ID be taught as an alternative?
It's not science and it doesn't have evidentiary support.

Your last point is invalid, or at least impossibleyou can breed different "breeds" within a species, but you haven't changed the species. You can't have them "breed into" another species.
GOOGLE SOMETHING. I'm literally amazed you've had people telling you we've literally seen this happen and haven't even the curiosity to check that you might be wrong about a subject you've never studied. Explain that to me I'm really curious about how that happens.
Dobzhansky and Pavlovsky (1971) reported a speciation event that occurred in a laboratory culture of Drosophila paulistorum sometime between 1958 and 1963. The culture was descended from a single inseminated female that was captured in the Llanos of Colombia. In 1958 this strain produced fertile hybrids when crossed with conspecifics of different strains from Orinocan. From 1963 onward crosses with Orinocan strains produced only sterile males. Initially no assortative mating or behavioral isolation was seen between the Llanos strain and the Orinocan strains. Later on Dobzhansky produced assortative mating (Dobzhansky 1972).
Gottlieb (1973) documented the speciation of Stephanomeira malheurensis. He found a single small population (< 250 plants) among a much larger population (> 25,000 plants) of S. exigua in Harney Co., Oregon. Both species are diploid and have the same number of chromosomes (N = 8). S. exigua is an obligate outcrosser exhibiting sporophytic self-incompatibility. S. malheurensis exhibits no self-incompatibility and self-pollinates. Though the two species look very similar, Gottlieb was able to document morphological differences in five characters plus chromosomal differences. F1 hybrids between the species produces only 50% of the seeds and 24% of the pollen that conspecific crosses produced. F2 hybrids showed various developmental abnormalities.
At reasonably low concentrations, copper is toxic to many plant species. Several plants have been seen to develop a tolerance to this metal (Macnair 1981). Macnair and Christie (1983) used this to examine the genetic basis of a postmating isolating mechanism in yellow monkey flower. When they crossed plants from the copper tolerant "Copperopolis" population with plants from the nontolerant "Cerig" population, they found that many of the hybrids were inviable. During early growth, just after the four leaf stage, the leaves of many of the hybrids turned yellow and became necrotic. Death followed this. This was seen only in hybrids between the two populations. Through mapping studies, the authors were able to show that the copper tolerance gene and the gene responsible for hybrid inviability were either the same gene or were very tightly linked. These results suggest that reproductive isolation may require changes in only a small number of genes.
Digby (1912) crossed the primrose species Primula verticillata and P. floribunda to produce a sterile hybrid. Polyploidization occurred in a few of these plants to produce fertile offspring. The new species was named P. kewensis. Newton and Pellew (1929) note that spontaneous hybrids of P. verticillata and P. floribunda set tetraploid seed on at least three occasions. These happened in 1905, 1923 and 1926.

And, the argument y'all used that there are certain traits passed along, which helps "prove" evolution could be argued either way. I would submit it actually helps "prove" creation or design since, an engineer usually keep qualities from one entity, while making a similar entity. Why start from scratch every time?
An engineer wouldn't keep the bad, and he wouldn't modify unnecessarily. Our chromosome #2 is a great example. You can see where it merged from our ape anscestors. There is no reason a designer wouldn't build a normal chromosome rather than have vestigial merger points.
