Some people have views of God that are so broad and flexible that it is inevitable that they will find God wherever they look for him. One hears it said that 'God is the ultimate' or 'God is our better nature' or 'God is the universe.' Of course, like any other word, the word 'God' can be given any meaning we like. If you want to say that 'God is energy,' then you can find God in a lump of coal.
No matter who you are, engaging in the quest to discover where and how things began tends to induce emotional fervor—as if knowing the beginning bestows upon you some form of fellowship with, or perhaps governance over, all that comes later.

Yes, the universe had a beginning. Yes, the universe continues to evolve. And yes, every one of our body's atoms is traceable to the big bang and to the thermonuclear furnace within high-mass stars. We are not simply in the universe, we are part of it. We are born from it. One might even say we have been empowered by the universe to figure itself out — and we have only just begun.

… man has flown in the face of everything he knew time after time. He knew, not too many hundreds of years ago, that the Earth was the centre of the universe. He knew, less than thirty years ago, that man could never travel to the other planets. He knew, a hundred years ago, that the atom was indivisible. And what have we here—the knowledge that time never can be understood or manipulated, that it is impossible for a plant to be intelligent. I tell you, sir...
The universe... won't be measured or equated without making man feel bestial and lonely.
Two possibilities exist: Either we are alone in the Universe or we are not. Both are equally terrifying.
