I agree with you that Einstein's relative time explanation does not change the fact that events that interact usually happen serially. Putting side the Space-time continuim for a moment, when we have a cause-event chain we candefine time as the order of chained events. Using this method we can reasonably ask what happened before the big bang by asking what caused it.The model I propose is one where we have at least two times. The first being the scientific space-time of physics and the other the causational order of events.Lie our spacial dimensions there may be a mulitiyde of physical times but there mighty only be a single causational time chain starting from a first cause, which like the first domino in a collapse chain is the first to fall and start the chain reactions.I am suspicious of models that have circular time. Godel proved that loops in time are possible but I suspect that initializing events are needed to start such loops. Such loops may be like Einsteinian time, with reverse time allowed but I suspect causational time would still have to be operating. Events always have causes and causes always precede events. Admitedly Quantum Mechanics allows time reversal or future to past causation but the future being referred to is Einsteininan time and causal chains still can be made. E.g. If we perform a test of an undecided state which causes a past event to become decided we can argue from a causational standpoint that the past event did not happen until after the quantum collapse.To understand what I mean let us assume that I will make a time machine in the year 2015 and go back in time to 2010 with the instructions on how to make the time machine. If I then make the time machine in 2015, I may wind up with a Godellian time loop. On the other hand if my going back in time causes the time machine to be made in 2011 we may have a parallel worlds scenario, or a time revision. If time is revisized the first revision would be before later revisions in causational time. Another way of explaining it is if you went back in time as an adult and visited your child self the you the adult would remember the future self of the child. The order of event that hyou remember such as the time machine being made beforeyou visited your younger self, would be the causational order of time. It is possible that there was a first event that just was that started everything but finding the cause of the uncaused initial cause, is something that might alsmots stump even a genius like myself.Circular time is often put forward to solve this dilemma but even if we have circular time the problem exists as to where the circle came from. In the end we must always wave our hands and say "it just is".This reminds me of a story about a supposed Philosphy exam. There was only one question: "Why?" The stort goes that most students filled pages of arguments but the person who got the highest marks answered "Why not?"This is obviously a myth but If we do go back to an ultimate cause with no reason, this reply is as good as any.Thus it may be conceivable to have an infinite causational time that begins with the first uncaused event.
