In that case, if good/evil are subjective, then there is really no such thing as good/evil, since everyone's definition would be different.
Noooo. It doesn't mean that they don't exist, it means they are subjective. Subjective things exist. Even one better, societies tend to have intersubjective morality, in that the majority of individuals have similar morals. As in, most people believe stealing and murder to be wrong, ceteris paribis. It has never been the case in any society that everyone's morality is completely different from everyone else's. Intersubjectivity makes morality within a society possible. And within any given intersubjective system, objective statements can be made, which makes situational ethics possible.
So the whole Christian gotcha of objective morality is a non starter, and frankly pretty silly.
If good/evil are objective,
They aren't.
which they must be in order to exist in any meaningful sense,
They don't.
then we're back to where we started, meaning that you have to prove what good/evil are.
You would if you were right. But you aren't...
