Pre-big bang (PBB) can only be explained philosophically...there are no experiments that could test the PBB period. So, having fertile minds, physicists have been busy conjuring up all kinds of speculations. They are fun mind games, but have no tangible evidence to validate any of them.
Brian Greene, in his "The Elegant Universe," has conjured up one view of PBB. Parallel universes, like so many slices of bread in a loaf, are feasible according to string theory (actually a philosophy). In this view, the big bang might have occurred where/when two empty (null) universes collided (which implies space, motion, and, thus, time during the PBB). Such a collision could account for the unimaginable energy it would take to create a big bang and our observable universe.
So, to directly answer your question, according to the parallel universes concept, our observable universe expanded into a null universe that pre existed the big bang. And, contrary to your assertion, space and time did exist prior to our big bang. (Understand, though, space may not have been the same space you and I have come to know and love. And time might have been different as well.)

The physical universe is the anomoly. What exists before it is the natural state of existence.
Time is a consequence of the existence of light. It has been established that light exhibits properties of mass in that it appears to bend in a gravitational field. Light "moves" at light speed (according to present theories). We witness and theorize that as a massive object is accelerated to near light speed (C), time dilates. If anything could be accelerated to C it would be moving an infinite distance in zero time. This means for light, no time passes no matter where it goes. Anywhere it goes, it takes no time to be there, and it is already there. Because it has mass, the light can't be in the same place at the same time, so it exists next to itself in time, then next to itself in time continuously. From its perspective, there is no space, only existence in a stream of time. This light has eternity to change its form as a positive or negative energy field, appearing as an electron and a proton of atoms, the same energy of light then has an eternity to be that nucleus, the fields around it, the atom next to it, the molecules the atoms form, the bodies and planets and stars these atoms and molecules make up, filling the entire physical universe, and still for the light no time has passed. But for us, we can only see what the light was then, always and only in the past. It takes small fractions of time for light to reflect from anything we see to get to our eyes, by that time what we saw is in another time, it is no longer when we saw it. We are really looking at the exact same light we are made of , what is more we are seeing it with the same light it is made of and we are made of. For that light, it has an eternity to exist and fill all space in zero time, we observe all this as unique bodies in motion. It is an illusion.

I imagine there probably was a black vaccuum...and time defined is a sequence of events. There was no time before human beings invented the concept. I'm sure there were events occuring in a foreward fashion, and therefore, there must have been time.

If it was 'mind only' that existed in the beginning, well, that would rectify the science vs religion discussion. It existed in God's mind.

The answer would be no; because space and time are inextricably linked to each other in ways we don't yet understand.

yeah i've wondered how they determine that the universe is expanding. expanding into what? where's the universe-nonuniverse border and how is it defined?

This is a question that we may never figure out although the theories are endless.......

There won't be any life existence on earth. Eventually, there won't be any earth hahaha...

i must have missed the big bang when it happened, sorry!
