Marvelous!
The animation itself was very well done, but the concept was far greater. The travel through time up to the present was nice, though I was expecting you to pull something spontaneous to satisfy the childish minds of the vast majority of Newground's fresh wave of Family Guy obsessed kids. Instead, you chose a different route, traveling further into what we've yet to experience. The crazy thing is, it made sense that the humanity would perish, and yet would proceed to reignite as a far brighter light than before. It's as if we were flames in a fireplace, slowly growing, and then stomped out until but a few sparks remained. I then picture a few sparks wondering out into the house, one of them landing on carpet, and eventually evolving from an insignificant scrap of little to no value, into a magnificent blaze of might. The best part, though, was your depiction of the evolution of the human anatomy itself, eventually morphing into what we often visualize extra-terrestrial beings to resemble. And then came the theory of aliens inventing ancient architecture. :] I also loved how perfectly the replacement of the last word in the phrase "Beauty is..." fit each and every time.
To put it simply, this was truly fantastic. I rarely give 5/5, but I certainly will for this work of art. I won't even comment on any flaws, as the product was far too captivating for me to critique it - which, again, is something few are able to do to me. Like humanity, this submission was so simple.. Yet so complex.
