Also, in regard to your comment on why we find evolution so "offensive" it's because we believe in true science and facts, instead of a hopeful faith in evolution.
If you require "truth" and "facts" from science in order for it to be believed by your standards, and if evolution does NOT meet this criteria, can you please give us a few examples of "true" science? Perhaps even ones that are relevant to the origin of species?
Is gravity a "fact" with "true science"? Cuz that's a theory, too...
