Is there life on other planets

Scientists have investigated time and time again in search of the ability to live our lives in other planets. They have not specified at any moment that they're searching for living creatures similar to us. All the research you've mentioned goes back to whether we can live on such a planet or not. The evidence proves that it is possible for human life to exist on Mars, not that life DOES exist elsewhere other than on Earth. Mars might be the only planet with similarities to Earth so it's a farfetched idea to believe that life is possible on some distant planet. Of the 9 that we know of [including Pluto, still] we have yet to find anything other than water and life possiblities. No actual life to base ideas on. As for the images...the internet is never an appropriate source for research. With the access to technology people have these days, an ordinary picture can be easily turned into "evidence" of some sort. Wasn't a short while ago when there was that "sign of big foot"? Didn't that turn out to be a total hoax? This is no different. Believe half of what you see and none of what you hear. Things aren't always what they appear to be. -Ghoulia Life is statistically impossible, but it happened here on earth. DNA mapping and taxonomy have just about proven that here, on a planet that is ideal for organic life; in the "goldilocks zone" distance from the sun, having the right basic elements, having a molten rotating core creating a magnetic field to protect life from the sun's emissions etc etc, life has only started once. Just once. Think about that. You the reader have a common ancestor with a geranium and a house fly, and every other species on the planet. We know pretty well what the earth was like 3.8 billion years ago when life is thought to have started, but even under laboratory conditions no-one has been able to re-create life. Many have tried but failed, and still are, trying and failing. So called synthetic "life" has been created but it isn't creation of life, merely re-programming of existing life. We have no idea how life started on earth. But it did, against overwhelming odds. Of course I am talking about life as we commonly think of it ; organic life. But how is that defined? I would say something simply that reproduces, feeds and evolves. I could write a computer programme (if I knew how), or build a machine (which I do know how because I'm an engineer) that satisfy these criteria, but is that life? Life could be based on other chemicals, other DNA, but it still has to have to the facility to survive, or more importantly to start. There are billions of suns in our galaxy, with even more billions of planets circulating them. Some will be rocky, perhaps with an atmosphere of methane or other potentially life starting gases, perfect for life you may assume. But a physicist's or astronomer's view is different from a biologist's. It's like saying "I must surely win the Lottery - look at all the tickets I buy? The improbability far outweighs the probability. If the universe is infinite then yes, life will exist elsewhere. But as far as I'm aware the universe is pretty damn big, but not infinite. What I'm saying is that yes, there might be life out there, but it's naive to assume that because of the number of probable planets and moons that could "support" life one should assume that life has started elsewhere.
