Physics because it teaches the universe is billions of years old and there was an explosion of space that we can trace the universe's history back to. It also teaches nuclear theory used by various radiometric dating methods so that has to go. Basic chemical principles have to be erased because they define how biochemistry, a link in evolution, works.
