I understand and see it as wordplay, the truth is that no time before the BB time began means there was no spacetime, and time begins with the BB. It is deceitful to say this is not true. No spacetime means no existence.
Space-time connects space with time, so space and time need to act as one; three legged race. Separated space and time is different. Instead of a three legged race, it is more like two separated people with four legs each running their own race.
The former or space-time connects movement in time to changes in space. The latter or separated space and time is not the same thing, since it allows the passing of time independent of space and vice versa. This is what happens in the imagination. I can pass time planning my dream vacation at the beach while sitting miles and months away. We cannot do this in the three legged race of space-time. Space-time limits you and slows you down.
Say you were going to build a bridge. Before you can start building a tangible bridge in space-time; tangible ground break, there is a lot of planning to do. Planning to build the bridge is not hard reality, since it is mostly images in your mind and computer, and there will be new contingencies and the plans may change. You may also plan far away from where the bridge will be built. There may even be two or more alternate proposals. It is not until you break ground; BB, separated space and time, become firm as space-time. This is where things slow down; there legged race of construction.
The BB defines when space-time appears; tangible universe. But before that space and time are not connected; planning the bridge that will merge into space-time. Separated space and time connects consciousness to physics.
Our imagination can come up with endless scenarios; fiction and nonfiction, with only a few scenarios possible in space-time; nonfiction. Before anything within the imagination can become reality, we need to figure out how to separate one from the other; fiction from nonfiction. Many people have tried to come up with perpetual motion machines, but space-time precludes these; no space-time bridge to nonfiction.
Since separated space and time has way more more options; both fiction and nonfiction, than connected space-time; only nonfiction, separated space and time defines higher complexity and higher entropy; more options. This higher state of entropy in separated space and time is the potential behind the 2nd law within space-time. Both stay connected.
If we went from separated space and time; extreme entropy, to joined space-time, since this will lower entropy into the simple state of a singularity, there will be a huge release of free energy. Lowering entropy releases energy. In terms of a reality example, Eureka moments ; bring us to a simple focus and gives us drive; exothermic, that can change reality; space-time.
If you think about the second law which states that the entropy of the universe has to increase and since increasing entropy will absorb energy, then the second law implies our space-time universe is bleeding free energy. This energy is conserved but no longer useful to the universe. If the universe could make us of that bled out energy, entropy could not increase. So where does this energy go? It appears to be heading back to where space and time are separated.
If we look at the quantum universe, it has many properties that can be modeled as space and time not fully connected. The uncertainty principle is where position and momentum are not exactly connected; space and time are separated since position is space and momentum involves time; looser bindings in the three legged race.
