Can somebody give me a good argument in favor of objective morality?

I mean, it's a really old debate, so I'm going to try not to get too wrapped up. However, I will say that I think it depends on what you think of as morals. Some things are inherently bad or unhelpful, but you have to be really specific. You can't broadly say, "Killing someone is bad," since sometimes killing someone is what's best for other living organisms. Morality isn't generally defined that way (bad or unhelpful). Morality is a more abstract concept defined by the individual, thus making it certainly, nearly definitively, subjective. I do think there are things that are objectively "bad" or "good" outside of morality. However, if you scale those things up to say the solar system or even the universe, they matter less, so maybe I'm wrong. We're pretty limited in our ability to see the big picture.
