Well said, I couldn't find any flaw in your reasoning it was quite thoughtful. But probability tells me that with billions of galaxies out there, there has to be one planet, probably more, but it least one that is like ours and can maintain and sustain life. It's like the lottery, I buy a ticket and I know my chances of winning the jackpot are virtually nil but I also know somebody somewhere will win, if not this week, the next week or the week after, or maybe the week after that. But it will happen, I know it will happen. And I can't prove it scientifically but I know there is a planet somewhere out in the universe like ours and someday in the future if we don't destroy ourselves from global warming or some similar catastrophe, someday in the future somebody will find that planet. WATCH THIS: Earth-Like Planet Discovered http://www.youtube.com/watch?v=vm2mmkUN1ss&NR=1 Researchers announced on Tuesday that they have discovered a new exoplanet that is more similar to Earth than anything ever seen before. An international team from the European Southern Observatory says the solar system Gliese 581 revealed a new planet labeled "E", and it's the smallest exoplanet ever found. Exoplanets are planets found outside our own solar system. While "E" is too hot and too close to the star it orbits around to be able to sustain life, one of its neighbors is located in the prime habitable zone. The planet itself, however, is too large to be made of rocky material. [Gaspare Lo Curto, Astronomer]: "The planet on the outer rim is actually inside a zone that is defined as habitable, which is the zone where water could exist in a liquid state on the surface of the planet." The first exoplanet was located 14 years ago, and so far over 340 more have been detected. Most of them are giants similar to Jupiter or Saturn, and are extremely unlikely to support life. The Gliese 581 "E", on the other hand, is only twice the size of Earth. The researchers say their findings suggest Earth-like planets may be very common, but new technologies will be necessary to find them. They have had some luck using radio waves or spectrographic measurements in the new HARPS system, but more advances are required. The new planets were found in the constellation commonly known as Libra, using the La Silla telescope in Chile. When a planet orbits, it makes a star wobble very slightly, and which can be measured by a special instrument mounted on the La Silla telescope.
