With how many planets are in the universe, I think there absolutely has to be! Once we have the technology for faster travel, I am sure we will know for sure. In fact, scientists found a planet called HD 40307-g just last year which is 7 times bigger than earth, but appears to be in an ideal location to support life.

There could be! Life on earth is so diverse and there is so much universe out there who knows what we haven’t discovered yet!
On earth there are bacteria and organisms similar to bacteria in a way called archaea that can live anywhere from really salty environments, to extreme heat, to the deep sea vents and even in the arctic ice! I think there is a possibility we could find a planet where some of these organisms could live.

Dear lovedhiren, emdimmo and geojarvis, you all seem very interested in aliens and extraterrestrial life and I appreciate your interest. Did you know there is a field known as xenobiology which investigates the extraterrestrial life and future of life on Earth? Scientists who are involved in this field are known as xenobiologists – super cool guys. It always starts with asking questions like you did. I encourage you guys to find more about xenobiology and maybe one day you might be a xenobiologist!
Coming back to your question, there is no direct evidence about a planet which can sustain life but everyday we learn more about planets. I just read today that a NASA rover named Curiosity announced that it discovered that Mars was able to support elementary forms of life in the past, which is one more step towards confirmation of extraterrestrial life.
I personally believe in existence of extraterrestrial life. In fact I already know there are aliens living in our world today and I had to privilege to work with one of them; a bacteria called Deinococcus radiodurans. Deinococcus which is known as world’s toughest bacteria is amazing as it is resistant against extreme cold and radioactivitiy. It possesses such a powerful self-healing ability as it reminds me Wolverine in X-men. Fellow researchers at Macquarie Uni have recently announced that they discovered an “Alien Slime”, which can live totally independent of outside ecosystem (under total darkness and extreme hypoxic conditions) in Nullarbor Plains of SA. More interestingly, NASA Ames research center invited a large group of synthetic biologists from all around the world (I was there, too) to discuss possibility of creating a super bug which can live in Mars (must be resistant against radioactivitiy, extreme cold and must live in Mars’ atmosphere) and produce oxygen and water. We all agreed that it is possible to synthetically create an organism that can live in Mars and guess what NASA is funding this research now.
So considering all these, I definitely believe there must be planets which can sustain life, if not we can create bugs that can create a life 😉
Hope that helps
