Where do atheists get their morality from?

[Red Celt]

Did you check the second link? It is widely accepted amongst anthropologists that the Neanderthals showed a particular reverence for their ancestors. This is considered by most to be the beginnings of religion within humanity.

I clicked the link, but I was going offline, so it was a case of tl;dr, I'm afraid. But I'm already aware of the theorised decoration of Neanderthal graves. If true, it shows a sense of mourning... but again this is all of a country-mile away from the claim that religious law preceded secular law. You have suppositions, not evidence. Yet morality amongst existing social animals can be seen and witnessed... today, with your own eyes. Minus religion.

You're arguing for this:-

1. No secular morality
   
2. Religion
   
3. Religious morality
   
4. Secular morality

And you have failed on premise 1. Sorry, and all that... but them's the breaks.

Yeah. I don't see chimps setting up cemeteries for their dead adorned with decorations to worship their ancestors (not like the later ancestor worship religions though, this were those religions in the most primitive form).
