Since Hydrogen (protons) were nearly all created just after the big bang - does this mean every hydrogen atom within us is 13.5 bn yrs old?
Just the astrophysics really - should be correct assumption as hydrogen (and helium) were the start point of all other elements then formed within stars. There must be a little hydrogen formed as a by product of atomic reactions (fission and fussion) but this I expect must be a tiny proportion of the total still left.
