Science is not merely a collection of facts; it is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe.
: Utilizing a rigorous process to build and organize knowledge into testable hypotheses and predictions about the natural world.
This is the dividing line between science and non-science (pseudoscience). For a theory to be scientific, there must be a way to prove it wrong. If a theory can explain everything (e.g., "The universe was created 5 minutes ago with all our memories intact"), it cannot be tested and is therefore not science.
