One is SCIENCE, one is MYTHOLOGY. One uses complex, testable, and repeatable scientific observations and mathematical principles, the other uses magical sky fairies and magic words. If you want your religion taught as science, subject it to the scientific method. The problem is there is nothing testable, repeatable, verifiable, or falsifiable when you invoke "magic" as the answer. String theory, the big bang, m theory, are the best solutions we have so far for how our universe came to be. (nothing mentioned in the bible about how the universe came into existence anyway bronze age goat herders couldn't fathom such a grand scale) Evolution is by far the best explanation for the diversity of life on this planet. The discoveries made in the field of genetics supports evolution. The fossil record supports evolution. Testable, verifiable, and scrutinized by a great many scientists trying their damndest to poke real holes in the theory. Darwin himself was reluctant to publish it because he didn't believe it, but couldn't find any flaws in it. Conflating evolution, abiogenesis and the big bang theory is a common mistake made by religious people. They are 3 separate things.
