Do you 'know' or believe?
Life that does not 'originate' from earth huh... maybe if there have been any attempts to replicate abiogenesis or similar processes in experiments conducted in space? any organism produced from such could be technically considered alien right?
Personally I am unsure if Alien life exists, let alone intelligent alien life; however given what we now know of astrophysics I am inclined to think it probable that the conditions for life exist on other planets and that on some of these the necessary chemistry>biology processes have likely occurred.
