The Validity of Testimony vs. Science in Understanding Truth

Very few things in life are determined as "true" strictly through the scientific method. Most of the time we rely upon credible testimony. There are many things we base our lives on today as truth that are not learned through scientific discovery. If you want to prove your birth, for example, you produce a birth certificate which is based on testimony, usually the testimony of a physician or person who helped your mother with your delivery. If you want to prove your marriage, you produce a marriage certificate, which is based on testimony, usually the testimony of the person officiating your wedding ceremony, etc. These are examples of the many things we hold true that can NOT be proven through scientific discovery.
