and if there are resets out there, is there anything that could make
a dating method think an event is older than it shows? After all, all
matter is eternal and many claim it is just billions of years old if they
can be off by an eternity one way why not off by billions of years old
the other way?

No. Read what I actually said -I said
IF there was a “before” the big bang then it would make no difference to the validity of dating -the ”IF” is the operative word here.
…After all, all matter is eternal. .….
Firstly, the “dating” of things in science generally doesn’t extend directly to the “dating” of matter itself -unless it is radioactive and therefore has a half-life, there is no direct measurement that anyone can make to show “how old it is” (even with that radioactive matter, it would have generally have been made from other matter through nuclear reactions and that matter wouldn’t have been so much “created“ as merely “transferred). We can only “date” non-radioactive matter indirectly by extrapolating from the known laws of physics and the current state of the universe to estimate how far back the big bang happened.
Secondly, even if the “big bounce” theory is correct, matter wouldn’t be “eternal” because, as soon as the “singularity” expanded and was no longer was a “singularity” , there would be no matter because, instead, there would have been just pure energy. Later on, when the universe expanded and cooled enough for matter to form, much of that energy would have been converted to matter and in accordance to the equation E=mc^2.
Therefore, regardless of whether or not the “big bounce” theory is correct, all the matter in our universe was still created during/after the big bang and, if there was a “before” the big bang, that same matter couldn’t have existed “before” the big bang (although, presumably, there would still have been matter before the big bang that was destroyed in the process? -makes no difference to the argument either way).
Therefore, there is no premise stated here to believe that our estimate of how far back the big bang happened is “a few billions of years off”.
Even if the “big bounce” theory is correct and the universe is eternal in that sense (although not the particular “universe” we are familiar with), how does it logically follow from:
1, the universe is eternal and the big bounce theory is correct.
That:
2, the estimate of how far back the last big bang occurred must be inaccurate
?
-that’s if that is what you are implying here?
