In general, I find assertions that concurrently assert a statement AND it's negation to be suspect.
In particular, your statement is factually inaccurate. Big Bang cosmology posits that time began along with space; there is no "before" the Big Bang, as there is no "time" in which to establish a temporal order until the "Big Bang" took place.
Your are quite correct. My statement was nebulous which is why I put time in quotes. I apologize for not being more lucid. Hawkings, Davies and a myriad of other astophysicits have demostrated that time and space originated simultaneuosly. The space-time theorem. Scientists finally seem to be where theologians have been for centuries. Not that they should give up the quest for discovering truth, or we will end up in another dark ages.
