"The sky is blue" or "the sun rises and sets every day" or "water is liquid" These are sentences that may seem to express certain facts, but they are actually some examples of the human illusion that we understand what is around us within an objective perspective.
All of our knowledge, facts, and understanding of things depend primarily on our human perspective. There is no such thing as a cosmic reality as long as we are unable to monitor all the available information in the universe.
I often read questions like "Why does the arrow of time point in one direction?" Or "How did mammals evolve?" And other questions that seem to be trying to answer something, but in fact these questions are within the domain of knowledge that has been classified "human" as facts, and therefore it will not answer objective truth questions.
For example, time has no direction. Time is a description of our subjective feeling about where we have been and where it is possible to be within the entropy context with which we interact physically.
In fact, there is no past and there is no future. There is only now that you are drawing mental blocks explaining your experiences. In it you store events that happened and try to predict events that might happen, but there is no physical existence of time, so the question about the arrow of time is not a real question.
You always live now.
“Mammals” is nothing but a linguistic classification. We put it to some organisms that we found that they share some characteristics with each other, but there is no such thing in the universe as mammals on the basis of a specific entity that differs from other entities. This way of thinking is a result of the adoption of moral thinking, whereby there is a specific framework for everything by virtue of it being made. This is a tree, this is a bee, this is a whale, and this is a fish.
“Types of bacteria” I read this phrase a lot, but if we stop at it a little and understand what bacteria are and how they reproduce and genes circulate among themselves horizontally, we will discover that the phrase “types of bacteria” does not mean anything objectively, only a sentence used by humans to express the existence of differences between bacteria .
The sky is not blue, but the human brain analyzes the frequencies of light reflected in the atmosphere as a "blue color". The sun does not rise or set, but rather we (the planet Earth) are the ones who seem to be moving.
Water is not a specific entity in itself, but rather two hydrogen atoms with an oxygen atom within a specific temperature to be a liquid, but if the temperature drops a little, it becomes ice or becomes a gas if the temperature rises. In fact, it did not change at the atomic level (only a difference in the movement of its electrons), but from a human perspective, the shape of the water changed to become ice (a synthetic creative thinking), and thus we began to treat the two different states of this molecule as if they were separate entities. We call this molecule "water" in its liquid state, as if the rest of the chemical molecules do not have a liquid state. Why is there no name for liquid nitrogen LN2?
In fact, the scientific method tries to dismantle human bias in understanding things and works to build cognitive templates that are as neutral as possible. But it is not guaranteed that we can analyze everything in a simple manner consistent with the human mind.
The universe owes us no explanation!!
