God is one explanation, and indeed, he answers many problems. But m,ultiple big bangs play off of a huge number of events, - a much bigger number, and indeed - an addage which does not meet Occam's criteria. 1 compared with an infinite number, in order to comply with a silly chance/unbelieving ideology.
God is infinite, is He not? Than invoking Him as an explanation invokes not a value of "1", as you claim, but a value of infinity.
Just as "multiple big bangs" is a
single explanation with "a huge number of events", so is "God" a single explanation[/i] with "an infinite number of events".
