I hope you're not insinuating I'm being disrespectful simply by voicing a conflicting opinion. Saying we all use faith is disingenuous, as the word faith has different connotations in different situations. I do not employ anything that could be considered akin to religious faith. There is no scope for that in my world view. If I can't come to an answer by reason and science I will just accept that I don't have an answer yet.
