It is nothing like you saying 'read the bible'. The reason being that Darwin references evidence and experiments that you yourself can carry out and see if you get the same results.
Whereas the bible is a bunch of stories that I have to take at face value.
You can try things out too "love thy neighbour" not in the literal sense but just be kind/ good on general. The stories as you would say can teach a lesson just like theories of scientists, you can apply it until someone comes along and proves it wrong.
Absolutely agree, the funny thing is, in order to build such large societies we had worked that out before religion came along to state the obvious. It is a good example to follow, I find I can be kind without the fear of a deity punishing me if I'm not. :-)
