Science looks at all possibilities and evaluates them all by the same standards of facts and evidence. That's why Creationism fails as a viable alternative to evolution. Creationism fails every single test of facts and evidence. Science is not perfect, but its methods do provide for testing and correction. Religion does not do this.
Evolutionary theory is just that theory, but it is taught as fact.
However, I doubt that any sane person will argue that he can justifiably refuse to believe that his face is in danger of a rather violent collision with the ground should he trip while running. There are enough solid facts to back up Creationism to justify it as a valid theory. Creationism's support consists solely of a few words in one book. Evolution's support fills libraries, museums, and research labs all over the world. Creationism can't make one single definitive and specific factual claim in its own support that is not demonstrably wrong.
