after browsing through the technology and science news over the net

"The absence of any noticeable life may be an argument in favour of us being in a simulation.... Like when you're playing an adventure game, and you can see the stars in the background, but you can't ever get there. If it's not a simulation, then maybe we're in a lab and there's some advanced alien civilization that's just watching how we develop, out of curiosity, like mould in a petri dish.... If you look at our current technology level, something strange has to happen to civilizations, and I mean strange in a bad way. ... And it could be that there are a whole lot of dead, one-planet civilizations." -Elon Musk-

On answering our curiosity of whether are we alone in the universe or are we not, I guess at some point we might find our self in doubt: could we be in some short of a simulation in which we could never reach the existence so far away it become mere illusion. But learning from our recent history, human are capable to generate an impressive progression of civilization by proving out this so called illusion into reality, and made it reachable and testable. I supposed being in the optimistic spectrum will be more rewarding, but of course with a healthy portion of skepticism along the way. And after scanning through (fun-browsing) the internet, there are a lot of connective invention that might someday brings human to an unpredictable new level. 
Personally I feel ashamed and humbled that I am not part of those human beings who brings a lot to the progression of civilization, and to the amazing probability of our species' evolution. But to merely anticipate the probability really takes you into a new philosophical areas. It makes the personal troubles of our life seems so much more insignificant and trivial. And in a brighter perspective, it brings a sort of empowerment in thinking that we are worth more than we are today; that perhaps someday we will be liberated into a new developed being, far more advance than our current being. Meh or I supposed I am just a hopeful geek trying to navigate my confidence in a hustle and bustle of contemporary competition :D.
