Time is a fundamental concept. Without it you would have no energy equations. Time is implicit in the units of the gravitational constant and so underpins gravity. If it wasn't fundamental we would have ignored it. A snapshot of events does not require time but our universe is not a static snapshot.
So provide your evidence that there was no time before the big bang. That should be interesting.
What was it Einstein said about that?
As for time not being fundamental try ignoring it. See how far that gets you.
If time were passing infinitely quickly then everything would be happening all at once. What was it Einstein said about that

Time only passes infinitely quickly where the the distance between objects is zero.

This certainly does not mean that past, present and future all exist at once.
Homework: What is the connection between the increase in entropy and indeterminacy?

Parts of the universe appears to be expanding and contracting at the same time. Black holes getting bigger and space expanding. Is this a contradiction in physics. Or are we, unless this situation changes, going to end up with near infinite space (and a consequent huge increase in entropy (think)) plus a single, enormously massive, point that is in fact a black hole . Note that although we have an expanding universe, the rate at which time flows stays the same (as determined by the speed of light). A photon that travels a certain distance in a certain time will take longer to travel the same distance in the future.
