Very good point, which draws up another question: Is this all just about perception? Thinking, looking, feeling, and smelling? If we truly aren't alone in this universe, which is very possible to say that yes we aren't alone, then what is another species perception like of the world around them. Because we have to remember, we are just an extremely complex composition of molecules that has taken a liking to wanting to understand itself, and shut out any alternate possibilities that could deviate us from that path, even if those possibilities could be factual, or right. Maybe, for just right now, for the time that we are aware of this state of consciousnesses, our physical and evolutionary make up is what drives our perception and awareness of our own "human condition". Perhaps we just aren't meant to understand yet, in the line of evolving, what is to come next. This all is very relative to time. Time meaning, on the evolutionary scale, we may be able to look back on this point thousands of years into the future, with a higher mental capacity and understanding, and say " oh yeah I remember when we couldn't comprehend what happened when this part ended."
