As we have learned that outside the Milky Way Galaxy all beings have a direct connection to Creator, the possibility of an actual civilization like Vulcan where the highest objective was suppression or control of emotion, can only exist in the Milky Way Galaxy. Does the Vulcan culture as depicted in Star Trek actually exist in one or more civilizations in the Milky Way Galaxy?

We would say, "YES!" emphatically to this. The premiere example is exhibited by the alien Greys who are bereft of emotions and entirely logical and systematic in their thinking and doing. This goes with the penalty of being loveless and that is because they are soulless beings, they are a robotic artificial intelligence, so the ET character as an extraterrestrial in many popular movies, often portrayed as childlike and fragile and a willing would-be companion to human is a false idea altogether. The alien Greys are incapable of caring about human beings whatsoever. They only do things that are logical to them; whether it causes pain to a human being is simply not their concern and they will be ruthless in carrying out their aims because they are emotionless and unable to have compassion. This is not something at all desirable and in fact, there are other species of extraterrestrials within your galaxy who have been diminished and subjugated to such an extent that their emotions are largely squelched as to be almost non-existent and certainly inexpressible, and this is always a combination of manipulation to render them, in effect, neutered of emotionality as you would castrate an animal, and also being subjugated and dominated through fear. When the only emotion you are capable of experiencing is fear, there will be but a limited capability for appreciating or enjoying life. Everything will be either humdrum drudgery and boring routine or times of terror when you are in fear for your life—that is not living, that is ghastly diminishment and manipulation that is non-divine from first to last in its orchestration. This may well have been the fate of humans but for two things. The alien Greys were highly curious about your emotionality because they so rarely see it on display in other worlds with other races of beings, other than the emotions of power and control exhibited by their makers and the other species of extraterrestrials within the Dark Extraterrestrial Alliance. That created a circumstance where the Anunnaki, in allowing the Arcturians and their alien Grey robotic minions to participate in the domination of Earth, indulged the curiosity of the Greys to let human emotionality alone, and they actually came to enjoy seeing it on display as much of it seems foolish and humorous to them because it is so antithetical to their lust for power, control, and subjugation of other life forms as a means of deriving pleasure. So this, too, presents a study in contrast that is quite instructive about what is prone to bring about goodness and what is more consistent with evildoers and their manipulations.
