Interesting video. I loved the music!
And for those questioning the moral/meaning, I think it's using the
idea of a baby forming in the womb as a metaphor for the various events
throughout history and how they shaped and formed humanity as a
whole. That's where the "Humanity's suffering is pushing it to its
birth" thing comes in. Our suffering only serves to help further us as
a species. Overall its a pretty optimistic video, since it's basically saying that no matter how we suffer in the future, it will only make our species better.
