He said SOME and it's true people do use "god" to fill in the gaps when there are no answers to give. Always have. It just goes to show how arrogant we are as humans. How we MUST have ALL the answers and if not. If we can not comprehend or understand.. Oh well then, it must be GOD doing that.
What? If people in the past who have little knowledge with anything in their world, how things work, why they happen, you can only assume they would think it's something supernatural. And even today. Most people aren't going to become scientists why do they need to know so much about dark matter(or anything really) other than what they learn how a pbs special? Most of this stuff will just be trivia. So, I think it's stupid to be "OH I FEEL BAD FOR THESE PEOPLE WHO BELIEVE IN GOD WHAT SAPS"
