I would think Elagabulus' statement can indeed be verified, simply because it is easily grounded in scientific conclusions themselves based on empirical data. If I read aright, any science-faith dialogue has to begin with the acknowledgment of scientific truths, which leaves plenty of room for speculation, whether faith-inspired or science-inspired. So it is a fact that light travels at a constant speed, but the anthropic principle (that evolution depends on so many happenstances that is must lead to humans) is a matter of vigorous debate. For Dennis Galon and others, facts can also be grounded on cognitional philosophy: whether one has experienced correctly, gained intelligent insights, and made rational judgments.
