Time in relation to motion, given that their would have been no motion prior to the big bang, would not existed. You still fail to answer both what caused the big bang, and even more importantly, how everything got to the state it was prior to the big bang. Big Bang Theory has no answer to either of these and there is nothing but speculation. Also, your "when there is no evidence, there is simply no way of knowing" is a very naive empiricist position dating back hundreds of years. Logical deductions through analytic truth require no empirical evidence whatsoever and neither do tautological truths. We know they are true by definition. When you insult philosophers in general, you just make yourself sound like a dogmatic religious scientist who most actual scientists would probably be ashamed of.
Plenty is beyond the scope of physics. Logical positivism died in the second half of the 20th century so you're still reciting decade-old scholastic views that have been falsified, refined, or straight up abandoned. Philosophy may (or may not) be the result of human minds and you may (or may not) be capable of physically explaining the totality of processes going on in the brain, but that is not philosophy at all. Philosophy asks different questions, and barring a few overlapping fields, no educated scientist is going to claim the pseudo-intellectual scientism position you have so much faith in that it is the all-encompassing holy grail of objective truth.
I don't know what your edit is talking about, I think you confused my post with someone elses because it isn't related to what I said at all.
Oops, I did edit the wrong post. Let me fix that, then I'll get to the rest of your response.
Alright, old post fixed, and ridiculous quote pyramid removed.
We have no way of knowing what happened before the Big Bang. There very well could have been motion. When referring to time physicists generally mean it in the sense of spacetime. I'm not sure what that has to do with motion. There's nothing naive about empiricism. Demanding evidence as a precursor to belief is part of the logic you keep harping about. The Big Bang Theory doesn't answer what came before or why it happened, because those are outside the scope of the theory. As I explained, the physics beforehand were likely different, so we need new evidence to explain what came before. The Big Bang Theory starts with the very first expansion and says nothing about what came before because that is unknown.
I never said nothing was beyond physics. I only said that physics has something to say about anything concerning physical matter. The things you cited as being beyond physics are things which have nothing to do with matter. I never said philosophers were entirely useless, or that they didn't have something to tell us about logical absolutes, etc. I'm just claiming that they have nothing to add to discussions about the physical nature of the universe. Calling them "navel gazing philosophers" was hardly an insult by the way. It merely implied that they use introspection, when examination is what's called for.
I briefly examined the Logical Positivism movement. It seems to have very little in common with what I've been saying, especially since I had the same objections to it that I subsequently read about other philosophers having. Would you care to explain how what I've been saying is an example of Logical Positivism? Also, I never claimed that physics is the one source of objective truth. For one my example of physics theoretically having applicability to philosophy was not intended to say that physics could do philosophies work. It was merely a throwaway reference to how many things interact with the physical world and can therefore be studied by it in some way.
I agree that no scientist would claim "that it is the all-encompassing holy grail of objective truth." especially since that is nothing like what I was arguing. I would say that there are certain spheres where science is the only source of real knowledge. It is the application of philosophy within these fields to which I object. This position is one to which most scientists I know would agree. (Yes, I know scientists. I am a geology grad student. No, I'm not making an argument from authority. I'm just saying that there are plenty of tenured professors, well respected in their field, who I've heard make these very statements.)
