I haven't time to copy/paste to all that you wrote.
But any action I commit in the past would innevitably alter everything connected to it in the future. For example - If I bumped into Jesus and tripped Him up, breaking his ankle, He may never have had made it to Jerusalem in time for Easter. That would change a lot of things.
If I was in the way as the shot cried out for Kennedy...
If I left a cigarette lighter on the floor nearby where I'd lit a fire and an australopithecene found it and started firelighting.
If I, by accident, mentioned to the US fleet that the Japanese were going to hit pearl.
If I told Guido he was going to get caught.
And so on.
In fact - There is nothing I could do that would not affect the subsequent timeline..Nothing.
Jesus might have had second thoughts, got Himself a couple of wives and bred like a bunny. All His offspring would have massive effects and theirs and theirs and so on.
Just breathing one breath of air that was not then breathed would alter the entire world from that instance on.
Anyway nobody can go back in time, we do go full circle and redo it all again though. Exactly and differently as everything and everyone.
So when you are George washington, you will do as He, but you will have no memory of who you are now to alter what he has already done. So technically - All the issues you have today with these constitutions and Bills are your fault in the first place, but not yet, this time anyway.
Have a great day David. I'm off to bed!
