If the Big-Bang happened 13.8 billion years ago, and matter cannot be destroyed, and our bodies are made out of matter, then our bodies are 13.8 billion years old. Change my mind.
Since a human is not created until it is conceived, the building blocks of a human do not exist before one is created. Matter is ~13.8 billion years old and is simply rearranged through time. Humans are organisms created from cells, which are created from matter. A human is the name given to a specific structure of matter, and is only as old as when that matter was rearranged in that particular way. It should also be said that we are made up of a large amount of energy, which is not matter. Energy is only as old as when it was created. So with these two pieces of evidence, I disagree with you.
Lithium just don't care. He can make a post like that and everybody wonders what's going on. But you will not understand. You can't. Only Lithium can. Because HE'S THE MAN!
