Maybe we are all characters in someone's book, and everything about us has already been in her mind. As she writes out her imagination, our colorful life continues. When the characters in it transcend her writing, she will most likely kill him in some unimaginable but reasonable way, but the premise is that the world of the novel cannot be destroyed. Maybe we are all living in a dream, and the person who created this dream is not like us proving his existence. Just like the characters in an online game, if there is no one to control it, and if there is artificial intelligence, they will never know what the so-called network is, and they will not know that their world is just data. Similarly, our world, or we are in a dream, do not know what is outside the dream, what is the creature that created this dream, and where would we go if we jumped out... Can you imagine all this? Just a fantasy?
