Whenever you come across the topic of evolution, ask a simple question: What definition of evolution is being used? Since evolution has at least three different meanings, it’s essential to know which one is being invoked.
For evolution to be a fact, you must have two things, minimally. First, you've got to have life coming from non-life--abiogenesis. Second, you've got to have a change in that life from simple forms to complex forms over time. You must have the kick-off, and you must have the rest of the game.
