I believe it has something to do with the complexity of how our neurons work. Defining complexity, I think it's when neurons don't fire completely randomly, or fire at the same time by coincidence, but when they do have patterns coming up, and, specifically, complex patterns (this time "complex" really is used in layman's terms). For this reason I can't say that my processor or, for a better example, some cellular automata programs (look up "Conway's Game of Life" for an excellent example) aren't also conscious, but in a different way to us. But I digress. I think if we are to look for something like it, it shouldn't be consciousness exactly, and perhaps not even self-awareness. If they are able to use reasoning, logic, maths, etc, then that should be satisfactory. Furthermore, if they want to find us, they must have some sort of imaginations (which, if organisms with some form of brain of "processor" does arise, I suppose imagination would follow, as it is useful for planning ahead, which is useful in Darwinian terms... Very useful infact).
