Not to seem like a troll but technically we are as old as the universe. It's been proving that our universe has been expanding ever since the big bang. I do think green leaves used one of newtons laws out of context, however, if you believe the big bang to be true then technically we are all made from origins of a star, which would explain why carbon and hydrogen are the predominant elements throughout our universe. As for 'our organisation of energy' it doesn't technically dissipate, as our body in some way or another affects our ecological system. By mentioning our energy just dissipates means life is spontaneously created without any correlation or links.
