My knowledge of the world

How did this world come into being?
Who created it?
Why is it so eternally moving and developing?
Is this world understandable?
But the uncertainty relationship in quantum physics also says that the coordinates of a microscopic particle and its velocity cannot be measured at the same time.
Are our human feelings, perceptions, and memories also part of the objective world?
So how can the objective world know the objective world itself?
What is the picture of this world?
If we abandon our personal consciousness, then there will be no more in the world—color, temperature, sound, etc., these are just our feelings.
If this world departs from our individual human subjective knowledge, then what is the meaning of the existence of this objective world?
In fact, it really has nothing to do with humans. This is how it exists.
