It's the replacement of a more-viable hypothesis (local abiogenesis) with a less-viable one (panspermia), for the purposes of intellectual entertainment. I personally fail to see the entertainment value of speculating about aliens fucking with the history of our planet. YMMV, Passer. Playing with shit ideas just because they haven't been ruled out is mainly the purview of philosophers, so you should probably first practice speculating about something that is of more immediate consequence to the fat part of the bell curve of theories (ones that are not quite so conspiratorial).
