I mean to know I am going to turn (or return) to carbon and oxygen and what not is not comforting at all.
Carbon has no feelings at all,
Atoms have no thoughts.
Add one here, subtract one there and you can turn one senseless unconscious life giving thing (like water for instance) into a deadly other unconscious thing like peroxide or what not.
Just imagine the million different elements one can find with only C, H, and O atoms:
some good some not so good and all unconscious.
All I can know, think, experience, see, hear, smell, taste, feel and ponder is in the here and now. Once chaos wins over the order of life and it always does all this is gone forever some think.
No air no consciousness.
