To begin with, there are several million teapots orbiting the sun: every teapot on Earth is doing it! Silly questions deserve silly aswers.
'Atheist' is a label I'm stuck with because people understand it, but I don't refuse to believe - I refuse to worship. Science is only part of it - it shows systems which seem to operate without a god, and are flawed in ways that throw doubt on the existence of a perfect creator. Then there is history, the long, dark and bloody annals of Humanity that make nonsense of the idea of a benign and loving god.
So that while I wouild be foolish to outright deny the existence of a Being or Beings of immense power who may or may not have intervened in, or manipulated, the development of our species, I do not, on the evidence I have, consider them worthy of worship. If, in fact, worship is what they want!
