Logic actually doesn’t suggest this at all. Such an alien civilization could exist...many of them actually, and we would probably have no way of knowing about it unless they intentionally reached out to us. And why would they? If they are really that much more advanced than us, we may hold no value to them(if they even know we exist) other than a morbid curiosity as to how our biology works. Or they may not want to interfere in our development. For all we know, we could be a Sunday night “National Geographic” type show on an alien home world where they get a kick out of watching us and our primitive ways..
