Can Stephen Hawking really claim that there was no time at all before the Big Bang?

I don't know how they could say a lone black hole equates or tends to a big bang when they also accept it emanates radiation.

edit: Unless I guess they take the effect to be diminishing as the black hole implodes and then not existing somehow (?).

using logic one can say that something can't just come into existance which means the energy from the big bang and time itself have always existed (I think Kalam's Law says something like this, I may have just used the law of sylogism). You could also make the argument that something can't just always have existed but time coming into existance and always being there is the same thing (irrelevant) since there wasn't anyone to observe before the big bang since all observers emerge from the big bang.

Unsubstantiated personal speculation is against the forum rules.
