@mikeymojo,
It is curious, if no information is ever lost, and reality never stops to progress then the Universe is bound to repeat itself ad eternum, and in it, any physical possibility will re emerge time and time again, so one might argue that non recurrence is in fact what is hard to believe in, as it is non rational...
Nature is full of recurrence everywhere around us from season cycles to evolution re inventing the same biological tools after mass extinctions because they work. The level of detail in recurrence right down to the individual level is just dependent on statistics and aeons.
