I believe that entities exist above, beyond, or outside human knowledge.
Human knowledge is small, not large. Humans mostly are innocent and/or ignorant — not aware, conscious, knowledgeable, wise, etc. Speculations about “outside existence” are mandatory from this preposition. If most of human knowledge (Humanity) is ignorance then hypothesis, theory, and speculation are necessary and normal. This is a truism; because speculate very often. People have a religious belief about the future, “The Sun and Moon, will rise and set tomorrow.” People faithfully believe they will live until age 10, 20, or 50. They claim to know such things. But these claims are disputed everyday. People unexpectedly die, on purpose or by accident. The sun doesn’t rise for everybody, tomorrow. This is the difference between implicit & explicit knowledge, inductive & deductive logic.
Most humans live by faith, in science or religion. Perhaps the rarest belief of all is faith in reason, in philosophy, faith through doubt.
Admitting that speculation is normal and commonplace, why would humans then presume singular existence throughout the universe? How did you come to the premise/conclusion that Earth, currently and temporarily inhabited by humans, is alone now, or has been alone forever? How could you even consider the possibility that human life is the only life throughout all existence, for all space and time?
You, like most humans, have thought too small. Human consciousness, and perhaps all living consciousness, begins in solipsism. The human infant, the baby, cognizes the world as a singular essence & entity, “Only I exist.” Humans teach babies this and indoctrinate solipsism into infancy. First a separation is created (Dualism). You exist and are alive. Everything else is dead. Only you are conscious. Everything else is unconscious. This creates solipsism, aka. the concept of ‘Idiocy’. The infant imbibes an absolute sense-of-self: self-consciousness. Because a division has sliced through the mind of the infant. I exist and other things may not exist.
“My existence is certain, as a thinking-thing.” (Identity)
Other objects, subjects, things, etc. are less certain than self. This is the premise and product of solipsism. Solipsism is a ‘hoarding’ or accumulation of life-force. The infant receives identity as s/he imbibes milk out of the mother’s breast. Identity, solipsism, self-centered self-consciousness, etc. represent life-itself. This is the origin of ‘Nurture’. Solipsism is the beginning, the building, the creation after procreation. Selfishness is gravitational, only pointing inward. All babies may experience this; therefore all lifeforms experience this.
From this (solipsistic) beginning, the biological law automatically becomes obvious. Humans religiously, falsely, only believe in its own existence. Nothing else exists throughout the universe. Aliens do not exist. Other lifeforms do not exist. All other things are “less alive” than humanity, inferior in-and-of life. Humanity receives all precedence, humanity first, all other life last. Humans definitely are alive and exist (as you and I exist), but this axiom is not applied to everything else. This is the duality of life, “I (Cogito) exist — but everything else may not.” This type of thinking is remniscient of infancy.
Many humans cognitively will grow and develop ‘beyond’ this stage of pathological solipsism. But some (a minority) will not. Some humans will remain solipsists from birth to death. This is most obvious in an infant who dies at age 3 or 4. But this is less obvious in a person who dies at age 80. How do people live their entire lives in this infantile solipsistic state of cognition/existence? The answer to this is mental slavery. Many people throughout the world (entire populations) are prevented from maturing beyond this intellectual infancy, due to various, nefarious forms of social stunting. People are prevented from growing (intellectually, mentally, cognitively) by their authorities (parents, peers, professors, presidents, etc.). Because solipsism creates egotism. Even parents do not want their children “to grow” beyond a point that threatens their own authority/autonomy.
That said, it should now make much more sense why humanity disavows/disallows any life existence ‘beyond’ humanity. Humanists will claim itself as the top and apex of all existence, not just on Earth, but throughout the un/known universe. This is the type of solipsism that encompasses and embodies Humanity-proper. The very ideal ‘of Humanity’ is stunting. You are not allowed ‘to Be/come’ anything but human. So humanism logically is obligated to deny Evolutionary Theory at some ideological sections. Because there is nothing ‘beyond’ humanity, nothing superior to us.
Humanity is the End of Existence.
The fact is now apparent. Humans will even deny known existence of entities/creatures outside of humanity. So unknown existential entities is a moot-point. Humans deny the gods as they similarly deny us. Gods are deities beyond human existence, outside the circle of human solipsism. Gods are the creatures/entities that ‘transcend’ human limitations/laws. This is known as Divinity or Divine Law.
There are laws of (human) possibility; but there are also laws of impossibility.
And humans currently rig this game of logic. What is impossible to humans, automatically is impossible to all other lifeforms, for all time, for all space, even beyond the unknown. Humans do not admit to un-knowledge. Humans are not humbled/humiliated by ignorance. Humanity is defined by arrogance, a false knowledge. The human/hominid specie is still infantile according to other perspectives, other lifeforms. Can you think ‘beyond’ or ‘outside’ yourself? Probably not. If you can then you are rare, very, very rare. Your mind maybe 1 in 1000000000. You maybe exceptional. But probably not, the probabilities stand against us all (me too). I am not exceptional too. I am human too.
Admitting this finally begins the possibility of divinity & deity. There is not just one abrahamic, christian, jewish, moslem god. There are many gods. There is a polytheism, pantheon, and plethora of impossible entities. But “We” (Humanity) neither wants to, nor can, acknowledge them. “Because nothing exists outside humanity. And if such creatures were possible then they must be inferior to Humanity, as insects, birds, fish, etc.” This is your humane solipsism, your automatic programming by society. You are disallowed from knowing the unknown.
To know the unknown, is my neo-paganism, getting back to basics, to my roots, seeds, core of existence.
