"When you come up with some real science (observable/provable/testable) rather than circular reasoning and "just so" stories that change day-by-day I might be enticed to believe."

Er what?

Evolution refers to genetic change through generations of species. Evolution is a fact since we can see it happening and test it. We can even cause such as by selectively breeding plants or animals for some trait. Try looking at the ancient form of a cabbage some time.

It can be observed in the wild in populations divided over islands, and in response to changes in habitat. It can be observed in the fossil record. It can be observed in the lab such as Lenski's long term evolution experiment on bacteria where isolated strains have evolved novel traits. It can be observed in fruit flies and other fast breeding species.

Evolution is tested every time a a fossil comes out of the ground and conspicuously isn't a chimera or animal that should not exist in its geological strata. It is tested and validated by fossils that have observable gradations of form including intermediates. It is tested by DNA analysis - Darwin didn't even know there was such a thing - yet it's exactly in agreement with the theory.

So no, there is no circular reasoning. Evolution is a fact and a theory. Anyone in disagreement is ignorant and/or a fool.
