There's no objective experience in life, no absolute good or bad. In science, there's no proof, no truth, and no facts.
All knowledge is a matter of perspective. And perspective depends on how we think about the world around us. Our whole universe is built on the collective thoughts of conscious minds. Everything we know about the world has, at one time or another, been constructed in the mind of a human being.
Without these collective minds, our knowledge would not exist. And if our knowledge of the universe didn't exist, would the universe itself even exist? It's the classic problem of a tree in the woods—if nobody is around to hear it fall, does it make a sound? If nobody is around to perceive and think about the universe, is it still there?
