Time

Just because something is huge doesn't mean that we cannot comprehend it; for example, it appears that the same laws of physics apply at all scales. Besides, even by going this far, I am letting you promote human experience over nature.
We exist in nature, so nature comes prior to our experience. Without any one of us, or indeed all of us, nature would continue; without nature, we would not exist.
What does it matter what I know? The world is there regardless. I want to know what I can know about it, but that won't be everything. If I am lucky, I will know the fundamental laws in my lifetime, although I cannot hope to know all of the facts.-Morosoph

I'm afraid your attitude is not even in common among natural scientists. Einstein won't think as you do. For example, how could you think that the same laws of physics apply at all scales? Newtonian mechanics only applies at our ordinary life, quantum theory and theory of relativism are needed in both microcosm and macrocosm to explain respectively. Natural science we seek for only solves questions in human sphere from micro to macro pivoted at our ordinary life. We might be able to pick a couple of shining sands at beach, yet haven't noticed the sea of truth lying before us.

Time has meaning whether we are conscious of it or not. To say otherwise is to conflate emotional purpose with physical existence and well-definedness. Emotional purpose and physical definition are both given the word "meaning", but they are very different things.
We become aware of time at birth, but our consciousness of time is just that: our perception of something that already exists. Few of us would believe that time began at the beginning of our own existence, a perspective that would be thought of as extremely arrogant. Yet substitution of general human experience seems to be okay. Quite apart from the unwarranted substitution of one person's experience with another, this appears to me to be arrogance on the part of humanity. We are not the only thing that exists.

I understand your entire argument here, but since I said that humans are the only being that can be aware of time in the first place, I say time has only meaning as long as it relates to humans. I mean for monkeys and birds or other living species, as long as they can't detect the sequence of time, time has no meaning, in other words, time doesn't exist. How can you detect time? It is impossible to detect time when we sleep. Unless we are aware, as it were time stops.

Do you still believe in time, are you going to say time can be measurable by watch? Are you going to say a watch or clock keeps on measuring time after all humans die away? No.
