Essentially, I agree that, “we’re only alone until we meet.” I could not have said that better.
In the movie Contact, Ted Arroway tells his young/curious daughter, “If we’re the only intelligent life in the Universe, then it sure is an incredible waste of space.” [paraphrased]
Lucasian Professor Stephen Hawking, whom I admire and respect, disagree on some salient points. I have read much of what he has written during his illustrious career, and I certainly respect his opinions and beliefs, but in some cases, I respectfully think that some of his more controversial remarks are based on his own lack of belief in the existence of a so-called “Creator” or, if you will, “Master Architect of the Universe.”
He is an avowed atheist, and I think that taints some of his statesments, regarding the existence of both the Universe, and the evolution of life within the known Universe.
For example, the link in the question to the talk he gave, has him saying, “The Universe can spontaneously create itself out of nothing.” [verbatim quote]
I disagree with that conclusion, based on the philosophy espoused by so-called Creationists, who claim that, quote, “The banana did not self-create!” I agree with that statement, in that something that doesn’t exist, can’t “make” itself suddenly come into existence. To do so, would be to imply that before the banana became a physical object, it was existing as some sort of spiritual intellect, and suddenly decided, “I will now become physical matter.” I don’t think so!
Likewise, the good professor claimed in his talk that, “We believe that life arose spontaneously on the Earth.” [verbatim quote]
I guess he has a mouse in his pocket, because of his use of the word “we,” unless he was referring to three entities: “me, myself and I.”
But, at least he used the word “believe,” so it didn’t sound as though he was stating a scientific fact.
Nothing can exist without being created, using the broadest-possible definition of that word, and everything that currently exists, had to have had a “start,” or “beginning,” IMHO. And, by saying that, I have to acknowledge that Gawd must have had a “beginning,” also, or He could not exist in “the here and now.”
It also begs the question, “If God had a ‘start’ or ‘beginning,’ then who or what created Gawd?”
One thing Professor Hawking stated, with which I concur, is that “Civilizations don’t last very long, but destroy themselves.”
It is the nature of sentient beings, I guess, to eventually allow themselves to envision themselves as Gods of some kind, based on their scientific accomplishments, and once they have elevated themselves to that level, they must eliminate all whom they consider to be their “inferiors.”
Enemy invaders for another planet will not have to do anything at all, to conquer our planet. They will just have to sit back and wait for us to cause our own extinction, as a species.
