Creationists and evolutionists, Christians and non-Christians, all have the same evidence-the same facts. Think about it: we all have the same earth, the same fossil layers, the same animals and plants, the same stars-the facts are all the same. The difference is in the way we all interpret the facts. And why do we interpret facts differently? Because we start with different presuppositions; these are things that are assumed to be true without being able to prove them. These then become the basis for other conclusions. All reasoning is based on presuppositions (also called axioms). This becomes especially relevant when dealing with past events.
