Quote:The following quotation from Hermann Joseph Muller's article, "One Hundred Years Without Darwinism Are Enough," explains the point.
"There is no sharp line between speculation, hypothesis, theory, principle, and fact, but only a difference along a sliding scale, in the degree of probability of the idea. When we say a thing is a fact, then, we only mean that its probability is an extremely high one: so high that we are not bothered by doubt about it and are ready to act accordingly. Now in this use of the term fact, the only proper one, evolution is a fact."

I'm a 7. It is a fact that God does not exist. We don't need to explore every nook and cranny in space to have relative epistemic certainty about the non-existence of God. Knowledge does not require 'absolute' epistemic certainty about something. If it did, we'd have to say that we have no knowledge about the behavior of the natural world. Clearly this is absurd. Theist complaints about the inability of absolutely disproving the existence of God are simply pulling a bait and switch. They apply one standard to knowledge in one or more areas of their life, and then pull out a completely different standard for disbelief in God. It's just a double standard.
