OK fine but hard science does not attempt to ‘reproduce’ history. There are many stories being conjured up and/or added to / subtracted from, but true science can ONLY repeat observations thru repeated experimentation(s).
Real, true hard science simply can not re-create history nor alter time in any way. No matter if there are 100 or 1000 natural clocks none of them are ever in complete agreement with each other, but the majority agree [1st link post #54] that the age for the Earth and Universe are in agreement with the written recorded history of mankind.
Their is only one true reality.
I agree with that. I would add that science is a process by which we start out knowing little about that reality, and by degree, over time, we approach an approximation of full knowledge.
