The problem with your rant, Is that evolustion is narsasitic in scope. survival of the fitest is everyone for themselves, because this is all you get, and kill everything that gets in the way.
My faith in a supreme being actually makes me more acountable to my fellow humans, because He has instructed me to love my niehbor as I would love myself.
Faith [and the ability to believe] are a gift from the Creator. When you use that faith for what it is created for, humanity is always better off. It is people of faith who have had the courage to withstand the proponants of tierany, often times at risk of thier own death, which is totally contrary to evolution.
