What justification is there for supposing that time and space were created at the time of the big bang (indeed, can you actually formulate a coherent event prior to the big bang that doesn't include time)?
It always amuses me that those who haven't spent any time studying or keeping up with developments in cosmology wheel out this trope about time starting at the big bang, despite the fact that the conclusion is held to be flawed by the two physicists who derived the conclusion in the first place.
The argumentum was absent my post, but the ignorantiam was evident in yours. I was asking a question, not making a claim. If something is claimed to have "always existed" the problem of infinite regression always applies. If something is claimed to have a beginning, the question of what happened before the beginning always applies. If, as some theoretical physics suggests, that time did not exist before the big bang, it offers a possible solution.
