Everyone needs to consider a distinct reality when throwing the word "alien" around. The term is a misappropriated definition, usually describing extraterrestrial beings, from a distant location in the universe. We are all related on earth, as well as in the universe. An illegal citizen of the United States is considered an illegal alien. An entity from another planet is considered an alien. In today's world of diversity, wouldn't that term be considered a bias racial term. Cosmic brother is a much more accurate, and endearing term. If on the chance "they" do exist, do we want to lump them in with border jumpers? I think we should try to stay on their good side.
The likelihood that all “life” in the Universe is related, is an irrefutable probability. It possibly even exists on a genetic level; nevertheless, considering the case that we’re completely different and distinct entities, it may be a matter of evolution’s Universal variations. If we all start out as the same seed of life; just like the same plant, in different gardens, will produce a better strain than another; “They” might be that same seed, having evolved in the best possible environment. The thought that we might actually all be related; that in reality (Every thing is Everything) and (All is One) are concepts we must consider. Just as we experience human variation; we in the Universe will experience life form variation, on countless different levels and extremes. Extraterrestrial variation will undoubtedly develop completely different living beings, with widely opposing agendas, and limitless physical forms; extraterrestrial life forms that would unquestionably appear “Alien” or “Godlike” to one or the other.
I agree with max. It's not all just coincidence we described "chariots of the gods" navigating the "heavens" in almost every known religion.
Whats the most rational conclusion:
1- every single religion shares a coincidental fabrication spanning decades and miles
2- religions are misunderstood documentations of an/multiple extraterrestrial event/s
3- Humanity is just the most intelligent species in our physical reality (that would be sad)
4- instead of a physical reality, there exists a spiritual reality; and although religion describes the exact same situation, there exists something else entirely? "GOD"
The only true "alien" is a consciousness foreign to our physical plain of existence. If in reality there is a "god"; by definition: he or they are alien.
If you like these concepts, read "The Angels of Armageddon" by George Forbes. It explains the possibilities of every one of these ideas.
