physical objects out of nothing; from a first-person perspective, we surely have no experience or idea of what that would even be like . Now, suppose that we do understand the notion of a mind creating something out of nothing. We imagine someone thinking very hard, with nothing in front of him; and then the next moment there is something, like a tree, in front of him; and, whatever this would mean, we imagine that his thoughts have caused the tree to appear in front of him. And remember, since God is supposed to be just a mind, without a body, that we shouldn't imagine a human being sitting there and looking like he's concentrating hard just before this tree pops into existence. That wouldn't be an accurate representation of the situation. We would have to imagine a mind , somewhat like our own mind, all by itself causing the tree to pop into existence. Now, we may be able to imagine this, in a way; but the question is whether we really are imagining a mind creating a tree out of nothing . Because, when we get to the part about a particular decision that causes the tree to appear out of thin air , we draw a blank. We have absolutely no experience of anything like that sort of decision. So one would doubt that, in fact, what we really are doing is imagining the creation of the tree with a mere decision. So that is one problem
