I personally hate labeling my beliefs most simply because I try to ignore the how it all started bits and focus on the what happened after that first second. I shake my head at anyone who thinks that we are a product of intelligent design, simply because my fundamental beliefs don't allow me to see that as rational. I've changed my beliefs quite a bit over the past few years as I've gotten more and more into astronomy and how our universe works, and tried to completely ignore the origins of it. All I know is we are continually working towards truth in science as best we can because that's what the goal of science is, truth. But with so much unkown out there, and with the scale of the timeline of the universe I find it foolish to think we have even a shread of capability to answer the biggest questions. The modern religions are a product of man over the past few thousand years, out of billions of years of the universe as we know it existing. Can you truely sit there as someone who is going entirely on faith and say "yup, this has got to be it". The people who are making the biggest steps towards finding the answers will always be the first to admit at the end of the day, they don't have a clue.
