Excerpt from Chapter V (Science and Religion) from The Scientific Outlook by Bertrand Russell

“Are we to infer from [accepting the hypothesis that the world began at some definite, though unknown, date] that the world was made by a Creator? Certainly not, if we are to adhere to the canons of valid scientific inference. There is no reason whatever why the universe should not have begun spontaneously, except that it seems odd that it should do so; but there is no law of nature to the effect that things which seem odd to us must not happen. To infer a Creator is to infer a cause, and causal inferences are only admissible in science when they proceed from observed causal laws. Creation out of nothing is an occurrence which has not been observed. There is, therefore, no better reason to suppose that the world was caused by a Creator than to suppose that it was uncaused; either equally contradicts the causal laws that we can observe.

…The purely intellectual argument on this point may be put in a nutshell: is the Creator amenable to the laws of physics or is He not? If He is not, He cannot be inferred from physical phenomena, since no physical causal law can lead to Him; if He is, we shall have to apply the second law of thermodynamics to Him and suppose that He also had to be created at some remote period. But in that case He has lost His raison d’ĂȘtre.”
