There are many who believe that miracles are proof of god’s existence. We hear wild claims that a healing has taken place but we never get an independent testimony from a medical office or a surgeon. We hear second-hand reports that someone was miraculously saved from disaster but we never get an eye-witness account of what is supposed to have happened. We hear rumours that prayer straightened a diseased body or strengthened a withered limb, but we never see X-rays or get comments from doctors or nurses. Wild claims, second-hand reports and rumours are no substitute for solid evidence and solid evidence of miracles is very rare.
However, sometimes unexplained things do happen, unexpected events do occur. But our inability to explain such things does not prove the existence of gods. It only proves that our knowledge is as yet incomplete. Before the development of modern medicine, when people didn’t know what caused sickness people believed that god or the gods sent diseases as a punishment. Now we know what causes such things and when we get sick, we take medicine. In time when our knowledge of the world is more complete, we will be able to understand what causes unexplained phenomena, just as we can now understand what causes disease.
