"Theories do not graduate to fact."
Exactly
If you're going to criticize the theory of evolution for merely being a theory to be consistent you should go forth arguing against Newtonian gravitational theory, the theory of relativity, molecular orbital theory, and the theory of quantum mechanics as well.
Since it is well known in science that a theory is never validated as absolute truth, the attempt to single out the theory of evolution in this manner indicates both an ignorance about science in general and a purposeful attempt to target one scientific theory for political and religious reasons, not because of any scientific objection.
