If it's about the pursuit of positive, life-enhancing ideas, actions and discoveries, then either or both or neither, depending! Some terrible things have been created/discovered by scientists and done/decreed by religionists. Some wonderful things have been created/discovered by scientists and done/decreed by religionists. We are an odd species, truly.

By the way, I'm personally inclined towards atheism and keen on evidence-based science. However I'm not some atheist fundamentalist: I can see and accept that there are plenty of good things done by religious people in the name of their religion, including many amazing acts of altruism, heroism and charity. Whether these people would still do the same if they were not religious, but just because they are good people, is largely irrelevant if in fact they do ascribe their actions to their beliefs. I also recognise that there are scientists with strongly held religious beliefs out there who don't necessarily allow their religion to blunt their sense of curiosity. There are also atheists with a very unscientific, gut-instinct-led basis to their atheism. Takes all sorts.

Finally, my partner's great uncle made an interesting comment just the other night when he said he happily believed in both god and evolution and didn't have a problem incorporating them both into his worldview.

Just some bits 'n' pieces for the pot...
