Q kind of has not confirmed nor denied it. Most he has said is classified and pointed out how far is closest sun. Let's be honest the universe is pretty massive to our minds. Its not far off to think they not only exist but probably already are here. I almost wonder if angels and demons are simply two different races of intelligence.
But no, not everyone is going to want to hear that, at least not yet. They will need to be pointed towards that reality over time. I just hope its in my life time.
