Religion and science ask different kinds of questions about the universe and its origins. Most Christians embrace scientific discoveries but in ways that differ according to Christian denomination.
Scientists use a standard procedure for expanding our knowledge and understanding of the world, called the scientific method.
This procedure, using experiment and observation to generate evidence to support or disprove a theory, is called empirical, meaning 'based on observation or experiment'.
Theories developed and supported in this way don't necessarily stay accepted forever. If new observations are made or new data comes along which disprove the theory, the empirical process must start again with a new hypothesis.
