Can you prove that the Devil isn't the right choice?

Well all I can tell you is that when I decided to study The Bible I came to realize one thing. Someone wrote it as an instruction manual for humans to follow to prolong our existence on planet Earth for as long as possible. I then realized that the devil hates all humans and wants all humans dead as soon as possible and would never write a book for mankind to follow that would prolong mankind's existence. So that proves to me that the devil is not the right choice for humans to make.
