This video is about Second World. Human are searching for quit a long time in universe, for a second earth (world). Yes, who tells us that our earth (world) is not unique? This also means that we need to be extra efficient. And take good care of our unique place in universe. P.S: In the song 'I describe' that, when we think, we have found a second earth so much light years from here. It may be so ‘that we (as in a mirror) just see our own earth ? ( who knows?) "but in a distant past. a-hum .. "it's just a thought …” but still. Be aware of consciousness.
