Faith is a person's perspective on himself or herself in connection to others, set against a backdrop of shared meaning and purpose. Faith is founded on profoundly significant abstract values, whereas science is founded on tangible propositions. Science can only explain what we know and not what we cannot know; therefore, it must limit itself to facts that can be tested through scientific investigation. Religion, because it is non-provable, allows for faith in things that we cannot see, hear, taste, or touch. Knowledge is information that has been proven true through research and experimentation. Knowledge is based on evidence and requires verification through additional studies and experiments. Science strives to create new knowledge and improve upon existing knowledge - religion simply accepts what it believes at face value without questioning its contents or circumstances. Science offers human beings a valuable tool for understanding their world and improving their lives. Science has enabled us to explore beyond our planet, learn how plants and animals work, and save lives by providing antibiotics and vaccines. At the same time, there are limitations to science that prevent it from replacing religious beliefs for many people. For example, scientists have no way of proving that God does not exist or that heaven will not be real once we die. It is important to understand that science and religion are different approaches to answering life's questions.
