Sorry Craftsman, but your arguments begs for counter arguments...
Before anybody declares religious war on me, i do believe in more between heaven and earth, just not in the validity of the three arguments presented.
First argument, cause and effect. Who said something (or somebody) caused it to *be* It could just be in a state of constant change. Take a look at a ring and try to explain where it starts and where it ends ? An unrewarding task.
Second argument, intelligent design. See first argument. With unlimited time for the universe should have learned its lesson by now and come up with a decent design. Ehhh.... how is it an intelligent design ?
Third argument, moral foundations. Its called evolution. Different species, different strategies for procreation and preservation of *your* particular genes. If evolution deems it a better strategy to avoid senseless killing in a species, it will become part of that species nature only to do it, if there is a perceived advantage in doing so (fights over food, girls, prestige, whatever)
Personally, I like to look for answers to the mysteries of life myself first, and if i can't explain it then, consider myself not bright enough to figure it out. And then try to look for metaphysical explanations.
I haven't figured out how to use the quote functions yet, but i dont blame that on a divine being... Its just one of those things in life, that if i persevere, i will find an answer to it (like rtfm)...
