Simple life I am certain is everywhere and the question is when, not if, alien microbes or protolife gets discovered. Occurrence elsewhere in Sol could well have happened as well.

Complex life has absolutely happened elsewhere in the galaxy, though I can see it as something that could be found hundreds of light years from earth. For that reason I don't see it happening at Sol again as there is just no good candidates for the kind of oxygen-water-phosphorus network needed for complex life to develop. Even Europa or Titan I do not expect to see complex life at.

Intelligent life would exist elsewhere in the universe, the closest example millions of light years from us and with technology gaps incomprehensible. There could be other intelligence in this galaxy anyways, but I would doubt them space faring so they would probably have civs currently resembling the kind of capacity humanity had in the ice age. And if we did contact them, they would be much more advanced by the time we did get to them as I would also picture them being tens of thousands of light years from earth. So you send a mission to contact the 'primitive' society that just had fire and paleolithic tools around 60K ly off only to find they're actually pretty advanced these days because 60 thousand years is enough time for a paleolithic society to become K2 capable.

If they are attempting communication and are close to us, they would have already succeeded so it seems certain they are not trying.

If there is another intelligence within this galaxy and it is not primitive, it would already be here in some shape or form and for whatever reason being non-interacting.
