take a minute to think about this- life is VERY fragile! the only reason we exist is because we are EXACTALY the right distance from our star (the sun) for a number of variables to be just right for life to form:
its not too hot or cold, so water stays mostly in liquid form (water is the universal solvent!)
its the perfect distance for the perfect temperature for life
the earths orbit is perfect - not too fast, not too slow, not too big, not too small
also, we lucked out and got a planet that just happens to have oxygen, carbon, nitrogen, and hydrogen (the 4 organic elements); these are key to creating carbon chains, which form proteins, which then form deoxiribonuceic acid --- DNA!!!, which through adaptation, and other evolutionary processes evolves into more and more complex life (like us!)
next, with the varitey of newly discovered exoplanets and the sheer number of stars in our galaxy, then with the sheer number of stars in the UNIVERSE! the probability of finding a star that supports a planet similar to ours is pretty good!
so is there life, consider how fragile life is, and the perfect situation it requires to exist and you can see the possibility.... having said that, evolution, and stellar formation takes a long time! and our universe is estimated at 13.5 billion years old (that means it took that long for US to evolve!) so the final answer, and it is purely opinion at this point of scientific exploration and knowledge; but i think so. one last thought- IF it does exist, its probabily not just like us, at the very least, its probabily just a patch of weeds growing on some far away planet in some galaxy not yet discovered! like i said, its fragile, therefore rare!
