The fourth question was kind of retarded. I'm surprised you actually tried answering it. Such pointless hypotheticals need to be ignored. If God can create a near-infinite sized universe (that works rather well), you can logically deduce that He can create a near-infinite sized rock (with relative near-infinite mass). Of course, that doesn't mean He would because there is no point. But the word "lifting" is incredibly careless (there is no specific up nor down in space). The correct word would be "move". But even if the near-infinite rock is moved, there is nothing else in relation to it in space since God is not present on the physical plane. So in a sense it wouldn't go anywhere. One should understand this all rather quickly, so it is obvious that this question is simply used to amuse the one who asks it (unless the person isn't very bright).
