Suggestions for atheist framework

[Minimalist]

For me, atheism simply means that there is no evidence for any of the gods created by the human imagination.

I'm hard pressed to work that into some sort of "philosophy."

I suppose the most I could offer would be to say that all of the assorted rituals which theists have invented to honor the god who does not exist can be dispensed with and the time saved put to a more productive purpose.
