Science is the best way by far to know facts about the natural world. But science says absolutely nothing about erthics or whether God exists. That is the purview of Religion.
Can't say I fully agree with this, on various levels.
First, I disagree
heavily that ethics is the purview of religion. Ethics is the purview of reason. And I'll add that this reason is also heavily informed by science - likely in far more ways that people who like to claim it in the domain of religion would care to admit.
Ethics / morals is fundamentally about well-being. Science has quite a few things to say about well-being. About how to distinguish well-being from suffering. In the extremes it's obvious, but there is a lot of less obvious things also. Also about what the causes of certain types of suffering are. To say it simplistically: if you don't understand the consequences of your actions, you will not be able to tell if and when you are inflicting suffering if it is not mega-obvious. So you actually need a good understanding of the world in order to be able to make intelligent and ethical decisions. You also need to understand the nature of suffering and well-being (both in physical as well as in mental / psychological terms). I'ld say that science is a quite important aspect to figuring that stuff out.
Secondly, I don't see how religion has anything useful to say about anything in general. I can certainly see value in story-telling, which is something that also commonly happens in religion - but by no means is it exclusive to it. And it that sense, I can see value in it. But not in a dogmatic way. I see it as a nice way to open a discussion about certain aspect of "the human condition", but by no means would I consider such to have any kind of "truth value" by default, just because it is "religion" or in the sense of "moral of the story".
