No, I don't think we can claim that we're the highest beings capable of understanding everything.
I agree. I think it's more reasonable to acknowledge our limitation or our inability to know that. But either way, that means we need to be open to the possibility
of miracles. Or if you have a hard time swallowing that word because of its connotation, maybe we can use another word - we need to be open to the possibility of an event that we cannot comprehend. And I think that's a much more reasonable position to hold... A position that acknowledges the grandeur and complexity of this universe that we live in.
