It seems that I am one of the few rational/positive/strong Atheists who believe that the Big Bang was not the commencement of the Universe at all. All Theist people obviously believe that the Universe was created by god, or one among many gods (like the Hindu god of creation, Brahma), otherwise there would be no point of believing in god. Atheists on the other hand can be split into two categories :
1) Those who believe that the Universe had a beginning (and therefore also logically an end). This beginning is typically associated with the Big Bang. All religious Creationists also believe in a universe with a beginning, which is why many Christians have no problems believing in the Big Bang theory.
2) Those who believe that the Universe is eternal (no beginning and no end), and therefore the Big Bang is no more the beginning of the Universe than the fission of an atom. It was just an explosion on a different scale.
This most essential division of eternal vs ephemeral Universe is one of time. Beliefs can also be divided for the limit in space of the Universe. Either the Universe is a finite entity. Or it is infinite in space. Once again, religious people overwhelmingly believe in limits. Creationists believe in a finite and ephemeral Universe.
For my part, I believe that it doesn't make any sense at all to think of the Universe as an entity that is spatially finite and limited in time on either end. I often feel disappointed when other scientifically-minded Atheists claim that the Big Bang was the beginning of the Universe. It is just another form of creationism.
It is undeniably the event that created our system of galaxies, probably everything that is visible to us in space. But why would it represent everything that exists ? If we take the analogy of the nuclear explosion for the Big Bang, if our galaxies, stars and planets are mere conglomerates of subatomic microparticles, how could we possibly perceive or understand the rest of the universe at a scale vastly larger, indeed infinite ? There may even be different rules of physics applying to each level of the Universe. Rewind the Big Bang until before the explosion and we might well have been energy inside a sort of atom from a higher scale section of the Universe, behaving with different rules of physics and chemistry as those at our own level, just like what we know of our subatomic particles (quarks, leptons, bosons) have different properties from those found at our supra-atomic world.
