God is the ultimate example of "might makes right" so he does have the right to lie to humanity if he chooses. Christians believe that he chooses not to do so, and it's not an illogical stance to take. After all, what does god have to fear with being honest? None of his creation can bring him to justice if they didn't like what he was doing to them. You listen to theists explain god's nature, and you get the impression that he's the sort of fellow who would have his henchmen saw your fingers off for some frivolous reason, and then make you thank him for it because at least he left you your palms. And forearms. AND HEAD.
"Well, evolution is a theory. It is also a fact. And facts and theories are different things, not rungs in a hierarchy of increasing certainty. Facts are the world's data. Theories are structures of ideas that explain and interpret facts. Facts don't go away when scientists debate rival theories to explain them. Einstein's theory of gravitation replaced Newton's in this century, but apples didn't suspend themselves in midair, pending the outcome. And humans evolved from ape- like ancestors whether they did so by Darwin's proposed mechanism or by some other yet to be discovered."
