Human rights come from a shared human feeling of empathy.  This has nothing to do with faith or a religion without god.

Why did it take so long then? Did people in the past have less empathy? It’s all social conditioning really. And regardless, it’s still “faith” in so far as there is no rational or scientific proof that we have a right to a fair trial etc. 
One might say they exist to bring about the most effective form of society. People function better where they’re rights are expected. That’s true at the moment, although let’s see if China overtakes the west. But regardless most people don’t believe in human rights in this pragmatic sort of way, they have a genuine faith that they really exist.
