This picture was for a journal illustration I had to do for a book called Sophie's World( useful philosopher textbook horrible novel). Anyway for the last Chapter the characters had talked about the universe and how the world and all things on it were, in the begining, the same substance. How when we die our scattered molecules become something else entirely. So throughout the existence of our planet we have each already been everything and soon will become everything else. I love talking philosophy! It's a passion.
