what would make the "theory" of a higher power less viable than the theory of evolution is the lack of supporting data a higher power has. There is little or no evidence that exclusively supports an intelligent being. IE. there is no evidence that cannot be explained by a more realistic theory.

Science judges it's theories by a few quantifiers, by how much data they explain, their ability to predict future information and how simple the explanation is (if we have two competing theories science will always favor the simples theory) . Evolution explains an extremely large amount of data. What is more impressive is that most of the information was discovered after the theory was thought up!
