Thought that in scientific circles it was always seen as more probable that some sort of alien life exists, at least since the 70es or so?
Also, I haven't seen a single piece of evidence that would mean that we aren't simply the product of some random chain reaction of atoms and subatoms that for some reasons thinks it has a conscience and is more than a cluster of carbon atoms reacting in, I admit, pretty spectacular ways. Meaning and purpose in a spiritual sense are concepts devised entirely by mankind, any higher, superimposed meaning of life would be an oxymoron in itself imo.
Of course only with what we know so far, but that should be a given in any discussion anyways.
