I can't tell how much of your sarcasm is based on taking me literally. I'm an atheist. I don't believe in an afterlife, and I'm always blown away when people say that without a "fear of God" or fear of hell, no one would act morally. Whenever someone says that, I'm like, well, I guess you want to kill and torture and rape people and you need this dumb framework to stop you from doing that, so thank goodness for religion. But personally I think we all have ethical responsibilities to other living beings, and especially to our own kind, which spring from appreciating the complexity of the world but can be completely attributed to rational, selfish, deductive reasoning and self-preservation, if you really want to get down to it.

Tl;dr you're arguing the fundamentalist POV that ethics can't exist without a God.
