What is Parsimony
Occam's razor (also written as Ockham's razor and in Latin lex parsimoniae) is a principle of parsimony, economy, or succinctness used in problem-solving devised by William of Ockham (c. 1287–1347). It states that among competing hypotheses, the one with the fewest assumptions should be selected. Other, more complicated solutions may ultimately prove correct, but—in the absence of certainty—the fewer assumptions that are made, the better.
Understanding Evolution says:
The parsimony principle is basic to all and tells us to choose the simplest scientific explanation that fits the evidence.
OK competing hypotheses and scientific explanations. Well materialism and its bastard child evolutionism don't have scientific hypotheses nor do they posit scientific explanations- no, innumerable improbable coincidences are neither hypotheses nor scientific.
Also innumerable improbable coincidences is by far the more complicated solution as it is akin to continually winning lotteries which is very improbable and therefor very, very complicated for an explanation. So complicated no one even knows what the explanation is.
That is why one coordinated design is by far more parsimonious than innumerable improbable coincidences.
