Metaphysical speculation is independent of the physical validity of the Big Bang itself and is irrelevant to our understanding of it.

What people believe impacts on what they do. And it's not as if religion is universally bad. Of course it's responsible for many peoples doing good actions.

People are interested in science, but they don't always know they're interested in science, and so I try to find a way to get them interested.

Of course, supernatural acts are what miracles are all about. They are, after all, precisely those things that circumvent the laws of nature. A god who can create the laws of nature can presumably also circumvent them at will. Although why they would have been circumvented so liberally thousands of years ago, before the invention of modern communication instruments that could have recorded them, and not today, is still something to wonder about.

For many, to live in a universe that may have no purpose, and no creator, is unthinkable.

I can't prove that God doesn't exist, but I'd much rather live in a universe without one.

The really important thing is learning how to sceptically question and rely on empirical evidence.
