Let me start by asking a question, is there a law in our world? I think the answer must be to say "of course it is"! Otherwise, what is our science for?
Then let me ask again, why is the law of our world "being" instead of "nothing"?
Is this question easy to answer? It's easy to answer, it's not easy to answer.
Digging deeper, this is actually a torture of the soul of all scientists who take the exploration of the laws of nature as their own responsibility. Eventually, there is bound to touch on one ultimate concept – God.
First of all, the word God here is not the God in the ** religious discourse system, but refers to the ultimate existence that created our world, to be precise, the "Creator", including the "God of the universe" that Einstein said he believed in.
Every civilization in the world has its own set of statements that "God created all things." For example, in the Bible, "God created the world in 7 days", and for example, in Chinese mythology, Pangu opened the world, Nuwa made clay to create man, and so on. However, since the development of modern scientific enlightenment, human beings have begun to tend more and more to logically related things, and even about the ultimate existence, they have also tried to narrate in the logical chain, which is the so-called "rational God". Thus, the statement that God is an alien began to move from "civil science" to "pre-science".
In fact, the most critical thing in modern people's logic is, of course, whether he has the superpower of "creation", and at this point, aliens are undoubtedly the best "candidates".
Whether it is the "seventh-level cosmic civilization" system or the "twelve-level cosmic civilization" system, the current human civilization (planetary civilization) is at the lowest end of the "survival food chain" of the cosmic civilization without any suspense, as long as it is one or two levels higher than our human civilization, then it is a matter of minutes to "surgical" or even "restart" the entire human civilization, and the gap between us and them is even greater than the gap between ants and our humans.
Therefore, there is no doubt about the superpower of aliens as gods. And Hawking has warned many times before his death, human beings should not take the initiative to contact alien civilizations, and they should also be afraid of the god-like superpowers of alien civilizations. However, Hawking seems to be worried about the harm to humanity caused by alien civilizations that are close to the level of human civilization, not our "God".
Of course, whether it is the God (aliens) who started our universe, or the God (aliens) who just created the "solar system goldfish bowl", there is still such a question: God (aliens) itself is **? Does "he" also have his own God (alien)? This is the thesis that made both Aristotle and Newton "big-headed": the first push.
Therefore, any question must be truncated at a certain point and cannot be asked forever. That is, the question of God about the God (aliens) of our human beings is not something we want to ask, but a matter of our God Him.
My personal guess is that the cosmic civilization of all levels is likely to be a "Russian nesting doll", and the cosmic civilization at a higher level is the God of the cosmic civilization at the lower level, and "he" himself was created by a higher civilization and has his own God (alien).
