If there is no proof of the central contention of evolutionary theory, species evolving (being created) through natural selection, then it is not “one of the best supported theories” in science. It’s pretty weak actually given the whole world and all species to observe . . .
Correct. Species evolve within their own species but do not evolve into another species. Macro-evolution is just as much a matter of faith as any other religion.
Part of the theory also is that this process happened over millions of years. You want to see it happen over a few decades.
