I view creationism as a scientific question. I view christianity as a theological question. Whether or not creationism is true does not affect my judgement of Jesus as the Christ. I do not accept either one, but for totally different reasons. I hope that is always clear in my posts.
Nice try, doesn't work. The Raelians claim I am the objective evidence of alien design. The Hindus claim I am the objective evidence of reincarnation. Quite simply, there is no way for me to tell who is right and who is wrong. There is no objective evidence for the existence of God. I do not view this as a weakness, since theological claims do not require objective evidence. However, creationism (the creation "science" part) is not a theological claim but a scientific one. In this realm the lack of objective evidence is a weakness, as is the objective evidence that falsifies creationism.
The theory of evolution is an explanation of all of the objective evidence that we currently have. Since there is no objective evidence that God exists (or Zeus, Ganesh, etc) he is never considered as an explanation. That's how every branch of science works.
