I always think how arrogant humans are to believe we are the only sentient beings in this vast Universe of universes. We are finding habitable planets everyday and life seems to want to spring up everywhere. In the deepest depths of the ocean at unbelievable pressures we find life. On the edges of volcanoes and intense Heat we find life. It would be very strange if intelligent beings have not evolved on another planet in another galaxy.

Live long and prosper
