So I guess you don't believe in gravity either since it is not exactly observable?..only its effects...and the theory of gravity has quantitatively less support than the theory of evolution...and as others have pointed out, evolution is observable and has been observed...even in high school level experiments...or can you perform an experiment to demonstrat creation ex nihilo for us?
But if you want annoyances why is it evolution versus creation in the first place? It should be abiogenesis versus creation...or better yet, abiogenesis versus religious fundamentalist myths
