Hold on a second, not only are you confusing the argument by throwing in unnecessary qualifiers, but if you were more careful about the reading of Modulous statement that I was replying to, he mentioned specifically an ACTIVITY! The concept of "things" being impossible but "activities" being possible is YOUR dichotomy, not his, and I frankly don't know why you are attempting to make some distinction. If Mod wanted to say that there can be the possibility of something occurring without evidence, but there can't be the possibility of something existing without evidence, than this is an entirely different argument for him to make. But disregarding that, you are still all over the place with this reply.
There is no evidence (according to Mod's point) that one can or can not stack 10 Mazadas on top of each other. Therefore it can not be assumed to be possible.
