Good question..In the Beginning properly translated in Hebrew is In A Beginning.....I can only conclude/conjecture from that .one of many beginnings....I am clueless what he does with the probability of so many beginnings endings and ..infinities...a simplification of that might be..there are many mansions in my fathers house..sounds like quantum level stuff..Truth be told..one universe ..one infinity seems so short, like one leaf on a tree..but several trees in a forest of trees..now that's room for growth..
