“In science, parsimony is preference for the least complex explanation for an observation. This is generally regarded as good when judging hypotheses. Occam’s razor also states the ‘principle of parsimony.'” See http://en.wikipedia.org/wiki/Parsimony
In the post below (“Multiverse of the Gaps”), I point to a recent paper in which a Darwinist attempts to get around the extremely small probability (less than 1 in 10 raised to the negative 1,018) of life emerging by chance by invoking an infinite “multiverse.”
 The question for the class today is which is the most parsimonious hypothesis: One designer or infinite universes?
