Science is a way of understanding the world, not a mountain of facts. Before anyone can truly understand scientific information, they must know how science works. Science does not prove anything absolutely -- all scientific ideas are open to revision in the light of new evidence. The process of science, therefore, involves making educated guesses (hypotheses) that are then rigorously and repeatedly tested.
