"That the universe, as was once thought, expands and contracts indefinitely, one Big Bang collapsing into another one, seemed reasonable enough. But in both models of the universe, what caused the first Big Bang? Or was there a first Big Bang, any more than a last number? If there was a first cause, was there a first causer? Did Big Bangs just happen to happen? Can we name the first causer “God”? We can name it anything we want. I can name it after myself. It is utterly insignificant what it is called, because we would be giving a name to something that falls outside all categories of thought and must be unknowable and irrelevant to knowledge. So naming it is a futile enterprise. The word “God” is unhelpful because it implies it has a knowable definition."
