Is there another Earth out there?
According to astronomers, about half the planetary systems may have worlds where people could live. Current technology doesn't allow telescopes to see far enough for us to study these planets. However, in 15 years or less, we should have an answer.
Do you believe humans will ever inhabit another world? With the current threats of global warming and overcrowding, would you consider leaving Earth? If we colonised another planet, who should be allowed to go? How would we build civilisation from scratch? How could we prevent another global-warming catastrophe? And does this mean there may be aliens after all?

yes, lots of earth like planets, if we look far enough. some will be younger, with dinosaurs taking precedence and some will be older with robots or nanotechnology ruling it.

I would think so, with an ever so slight variation.
