have you ever seen a picture of a human brain cell's atom? it looks like a picture of our galaxy. could it be that each brain cell's atom could be home to another universe such as the one we are living in? are we just a brain cell of a higher being? is our existence to small compared to what could be out there? yes.
Well lets just focus on our own galaxy for now. We keep finding new extra-solar planets all the time, they're usually gas giants. But as we get better at this we'll start finding planets in their star's habitable zone, that's where we'll find life.
Of course there's life on other planets, there is no way we're the only ones in the universe. And I'm sure there has to be intelligent life too, other planets like Earth. But we probably won't be able to discover any of these, at least not in our life time
There are other planets. The question of life has not been answered. I suspect there will be found other life, because in light of many past extinction events, life on earth is so hardy that there appears to be a drive to life. If its possible for life to exist, it likely will. If there is other life, it's possible it's not aware (or even carbon-based). It took billions of years (many say) for mankind to develop; who knows how many years a foreign intelligence may take to develop? I am skeptical until proof is provided. So far, SETI is a complete bust.
Could there be? Yes. I think anyone trying to place a probability to that fact is naive. The number of variable involved in creating life are currently beyond our comprehension. Consider that scientists have been trying to create life in labs for decades with no success. These are intelligent individuals with a set goal of try to create life, they are trying to take chance out of the equation and still can't do it. There are simply factors necessary for the creation (and sustenance) of life that we just have not discovered or pin-pointed. Without knowing exactly what it takes to make it happen, it's impossible to put a probability to the question.
Yes of course, but the likelihood of them having any human characteristics is slim. Think about it the majority of creatures on earth don't have our concept of a face or eyes or a mouth. Other aliens might just be bacteria or maybe bug like creatures the worm really has no actual face. They probably wouldn't be very human like.

Absolutely yes! the rough estimate (by astronomers) is that there are 100 000 000 000 earth-like planets in the universe. It is selfish to think that we are the OWNERS OF THE UNIVERSE. I believe that on one of those 100 billion Earth-like planets some aliens are discussing this very question as well :) and if we assume that the theory of multiverse is true, then there could be much more than that.
There IS a planet that's very similar to Earth, though I believe it's in The Milky Way. It's six(I think) times larger than Earth, and has a smaller star than our Sun, but it is in the perfect area to have liquid water, just like Earth does. If there's one in our galaxy, I'm certain it could happen in others, especially when you consider the size of the universe. Planets within solar systems within galaxies within clusters of galaxies within super-clusters of galaxies within a universe within the possible multiverse! It has to be true, quite frankly, and the math proves it.
Actually, yes, there may be. Because there are so many galaxies in this universe, trillions and trillions, at least one of them is like ours. And if there is a galaxy like ours, then in that galaxy is a planet that is in the exact same position relative to the center of the galaxy (a black hole) as our planet. And also a star that has a Sun like us, not so far away to cause it to freeze or close enough for it to burn up. So yes, most likely. But there is no real way for us to know because it is physically impossible for us to get a probe outside of our galaxy. It would take about a thousand years or more for us to just get it out of the galaxy.
