meh all life is an ever, changing, illusion. Some questions regarding the human situation, such as what is the purpose of the universe and our place in it? Really have no merit. That's like the equivalent to asking what's the shape of red, these things are not within scope. If one asked what are the factors leading up to such an event, that would be somewhat plausible. I don't think humans are suppose to know everything, and in turn induce stress over such unknowns. Its the mystery of life that makes it all worth living. I love science, but even specific branches of science have religious like followings.
God is a misleading word as it takes on a million identities, so in that case, no I don't believe in god, especially mono-dictacting god. But If I were to hear that God is Consciousness flowing through all, I might be able to feasibly grasp such a view, though its all metaphorical.
Naturally I find myself quite the pessimist, or skeptic, which isn't terrible as it keeps me open and searching for more. I do believe that organized religion is a big factor in halting the progresson and evolution of the human race. These are ancient Ideas, with little relevance. In the beginning God was primiraly invented out of fear, fear of death, among many other superstitions, as well as a device to control large masses of people
On the other hand religion has achieved some great things, but every system needs to be replaced and religion is one long past due. Although I must say, I do find a few some buddhist readings somewhat insightful and shares some views with existentialism/nihilism.
Anyways, Whether the universe has existed for ever or was created at some point, both theories are mind boggling. On life after death? The notion of existing forever freighntened me, but so did dying and slipping into nothingness. I'm just stoked I am of this world and get to experience the immense beauty and love it possessess. So whatever the outcome, enjoy.
