Yesterday, my dad and I were in the kitchen. I have a journal the I write his ramblings about, about his childhood, his coming to Canada, all sorts of memories since he has no childhood photos of any kind or souvenirs from his youth. So, I was writing away when he asks, "Who made man's blood red?" He's basically asking why god chose red for man's blood. I told him (and I was told this a long time ago, so correct me) that when your blood is exposed to oxygen, it turns red and that it's actually blue. He didn't acknowledge if I was right or wrong, but he just wanted a religious answer to his religious question and I gave a ration scientific one.
I find myself trying to answer religious questions with rational answers in general, not just from my dad, although they mostly come from him, but in general. To use a religious answer is to say you don't really know so your answer would be approved by your religious leader or 'god'.
I can see it as if I were to ask where babies come from and then told about the stork or the cabbage patch and then disregarding those answers, so to come from a religious state of mind is the reverse.
How often do you come up against these types of questions and how do you handle them?
