List of reasons to believe God exists?

[henryp]

Do you think sharing a species designation is enough to objectively invest me in the well-being of 8 billion other humans?

This isn't about being emotionally invested in the well-being of all your fellow human beings. The discussion is about what morality should be like, regardless of whether you choose to invest in that or not.

Doesn't that seem silly? It seems silly to me. But you need that premise for harm being objectively bad.

Nah, I don't need that premise to be true. That's open to discussion. Just be real with me, and don't give me an explanation that involves a practically non-existent entity.

1) I'm an atheist.  You're an atheist. Why do you keep bringing up what religious people think?  It's like tourettes with you people on here. 
2) The discussion is about whether humans being harmed is objectively immoral.  Which is tricky, because you're going to have a hard time pulling up morality in the lab.  So right of the bat, if you are a believer in science and 'show me proof', objective morality probably isn't for you.  But it sounds like you're just getting into this stuff.  I think you'll find that most people here think objective morality is dopey idea.  You just caught a bad break that the person you were taking the side of held such a lousy opinion.
