I couldn't see how there could not be some form of life some where in this humongous universe. There are billions and billions of stars and I would think that there would be at least a few planets revolving around most of those stars and a percentage of them would be in the "Goldilocks" area. And where is this area? It is different for different size stars, but the main thing that describes it is that the Goldilocks area is the area where planets can have liquid water. Now it doesn't say that they have to have it all the time at the surface, but if the water is frozen on the surface, there can still be liquid water under it. So, if one was to search for life in some form or another, you must follow the water trail. Water is essential to all life as we know it.
Some organisms can get the water that they need out of the air, but most need liquid water. So the possibility of liquid water is what astronomers search for on planets and planetesimals when in search of extra-terrestrial life. You did notice that I said "life as we know it". There is speculation that other forms of life may have evolved and live off of methane or something entirely different than what we do. Now, you all have a great day and watch out for all those other life forms, you hear?
