I dont think life is special but i dont think it is common either, based on observations of planets in other solar systems it appears that not much life exists, might i add, i am an evolutionist
You have seen other Solar systems? wow! you must be the first!(sorry) we have evidence that there are planets around other stars but we have not "Observed" and we may not for a long time. as of now we are contained in our sun's Solar system. So as I said life could be very common we just don't know it
