Oh, no! Not the stupid evolution controversy again! This is an issue that simply has to be put to bed! Enough already! No one knows how life began, but there is lots of evidence on how it progressed. There are important battles to fight; this is not one of them.
I disagree, Our belief in naturalism or theism is the cornerstone to our world view. Why would anyone who doesn't believe in a transcendent God who designed us for a purpose, believe in universal morality? Thus, moral relativism is the direct result of a naturalistic world view. We theists believe that their are universal laws and a power that created us for a purpose. These universal laws are both physical and moral. While everyone understand the severity of not following the phyical (gravity-if you jump off of a 10 story building you will perish), many do not see the importance of folling the moral laws (there are consequences to extra-marrital affairs...pain, broken marriage, STD's). Naturalists (moral relativists) do not understand how the system works and that a Creator made the system and created the laws so that the wise who heed them would be as free from pain as possible.
Sometimes I think the creationists are actually from DU and come here just to rile us up and waste our time.
