Interesting topic chimp. As a believer, no, I don't think anything can exist outside of time, except God. I believe God created time and before that it didn't even exist. How could it? How would we calculate what that time was if God was always in existence?
Now, how would this apply to evolution (if I assumed the big bang were true). What was time before the event??? Did it exist or did the Big Bang "create" time?
Also, I tend to agree with slev's post. For something to fit into time, it would technically have to have a beginning and an end. Would the 2nd Law of Thermodynamics have anything to say about this for those who know more about it then I do?
