No, no, I did not say that nothing happened before the big bang, there is no possible way for me to know that. I was talking about time in general and not time in relation to the singularity. I can't know if the singularity was in equilibrium or not, it could as well be not and time could exist, I can't know that. What I was trying to say is that it is possible for time not to exist.Does a lack of relevance remove the existence? I will agree that any time prior to TBB is probably quite irrelevant from a scientific perspective, because as you say, nothing happened(probably).
The length example doesn't land. It's like saying I got a clock that counts 12 hours but I can't measure anything greater that this. Which is false. If you have a measure, any measure, then anything that is measurable by this measure can be measured. LOL. Maybe you have tied time with your own existence very tightly and can't imagine it by its own. The arrow of time is highly related with entropy. When entropy reaches its maximum in a closed system then time does not exist anymore. I don't know how else to say it. Time is a measure, it's not a thing by its own.I get the impression that many of you go by "if we can't measure it, it probably didn't exist", is that right?
Does that mean that if I have a measuring tape that is 3m long, I can say that there is nothing with dimensions longer than 3m, because it is clearly unmeasurable for me? Yes, it is a silly simplification, but hopefully you get my point.
