In science, a theory isn't something that is false. A theory is a statement accompanied with multiple forms of evidence. Otherwise, it's just something that someone thinks about. If you have evidence, then it's what we call a theory. The theory of Evolution has plenty of evidence. Creationism? Not.
Religion defies common sense and logic and you can't win against them using those tools. Whenever something gets scientifically disproved, creationism claims that it has a symbolic meaning that we didn't know until it got disproved. Earth is the center of the universe, Rib women, and 7 day creation
There is lots of evidence supporting creationism. The fact that it does not line up with macroevolution- an unproved theory does not define it as false, it lines up with geology, the fossil record, DNA research and many other things. You can't base its truth off of evolution, prove evolution first
Biblical creationism as a natural/historical truth is not compatible with current scientific notions of historic fact. However, the ideas presented in the Christian creation story bear no incompatibility with science when interpreted as spiritual or philosophical rhetoric. Interpretation is key.
