I think it is possible for life to exist on planets other than Earth. I am a Christian though, and my views about aliens are basically derived from C.S. Lewis' Space Trilogy starting with Out Of The Silent Planet. If they do exist, and God is the designer of both them and us, then there should be common design features. Often taken for granted in science fiction, DNA is not chemically deterministic and neither are the patterns of the genetic code, so if abiogenesis were to be the source of life, such alien life would almost certainly not have the same kind of heredity molecule. Then ensues the ad hoc addition of panspermia if such life were to have the exact same molecule of heredity, deoxyribonucleic acid, whereby evos would rather evoke passage through space of the DNA molecules from one mega distant location to another just so as to reject the mere possibility of a common designer.
I have always hated how some scientists get all excited that "maybe life started on mars and came here on asteroids". Well, sure, maybe. But they get a little excited about it, positing theories when its just as likely, if not more, that it all started here. They are just looking for a creation myth, ignoring probability.
Note that I dont have a problem with the idea of amino acids arriving from space(I'm sure it happens). I dont even have a problem with life starting elsewhere. Its just that they get so damned excited about it, and discount that the basics of life
are here.
That being said, you have a point that there could be all sorts of life forms out there that we fail to recognize for the very reason that they are of a different basis from us.
