A scientific theory can never be proven. A theory is an explanation for observed facts. If you believ that a theory must be proven to be science, then either you do not believe in any science or you do not understand the definition of a sceintific theory. There are millions of pages of research published in the scientific literature of tests and predictions of evolution. THey are freely available in the libraries of any major university. Or, you can download them from the publishers for $10-20 per article.
I shouldn't have used the word "prove". How about "demonstrate"? "Demonstrate to me that Macro Evolution is a valid theory by testing it."
There, that's better.
