Setting aside the question of supernatural beings, which are not covered by SETI. We do not have any information pro or con on the existence of life off of Earth either within our outside our solar system.
However, if we do encounter a extraterrestrial intelligent life, some variation of number 3 will apply. Even if more technologically advanced, the odds are they will not be morally more advanced than us.
Humans remain as fallen as we were at the dawn of humanity despite our own technological advancement. No reason to think that any other intelligent species would be different.
If? What about clear examples of advanced alien technology and tactics which has consistently thwarted any and all attempts to produce a clear picture of any of their craft or occupants! Alien image blurring technology and tactics (AIBTAT) strikes again!
