Taking number 1 first, if it only created them, how might they explain us?;) Going on to number two, it is a well known fact, given it is only on earth, we have no knowledge of what goes on in the Universe, on other planets with life and how it is lived there, that a creature does not necessarily mess up where it lives. It goes else where to shit and piss. That may be a minimum level, but it seems to exist, even single celled creatures move on, it seems after having done so, but could be wrong on that. Would expect that at a minimum from another intelligent species. While they might not interpret it as loving the creation, it is at least caring for it.
Experience is what it is, their beliefs will be what they are, am fairly sure we can come to some agreement on co-existence within the Universe, but then again, maybe not.
