I repeat, the lack of understanding of something is not evidence for God. It’s evidence of a lack of understanding. And what we should do, if we’re scientists, or anyone, is try and say, “Let’s try and understand it before we go the intellectually lazy route of saying, ‘I don’t understand it, so let me assign it to an entity that I can’t understand, a divine entity beyond my comprehension.’” If I did that—If we did that we wouldn’t be in this room today, we wouldn’t be seeing these images because none of modern science would have happened. Instead we try and understand how things work, and the way science works is if there is a physical effect, we look for a physical cause. And so far, there’s not a single place in the history of science where we’ve been, we’ve gotten to a point where we can’t explain something and we know for certain there’s no explanation. Every time something was—every explanation that’s remarkable is remarkable for that fact: it explains something we didn’t think we’d ever understand. That’s the beauty of science.
