I posted the following comment on one of Blair Scott's latest lectures on atheism (which can be viewed on his youtube channel):
I'm actaully completely comfortable saying that I know there are know gods. The reason most people don't like to say that, is, I think, because they think that knowing implies knowing with absolute certainty. No room for doubt, ever. I don't see things that way. I'm comfortable saying that I know there are no gods for the same reason I'm comfortable saying that I know that evolution occurred. Neither one is known with literal 100% Certainity, but I think the evidence and arguments concerning both show that they are well over 99% likely to be the case. So I'm a high probability atheist: I don't say that there is certainly no god, just that it is really fucking unlikely.
