According to Big Bang from the cosmic egg. It cannot be created but it 'flows' from there. Consider the universe as a bubble which is expanding. One day it will pop. It might freeze and distingerate into the void before that. But it's highly unlikely that it'' come back. Ever. We don't know yet, but this is what it appears to be.
@FutureAstronomer the Big Bang explains almost everything but it doesn't explain:
1. What is dark matter and dark energy? Where did they come from?
2. Where did all the antimatter go?
Also it doesn't explain anything about what's inside a singularity or the flow of time but I didn't include those.
Edit: I don't think humans 'created' time. We were the first ones to discover it probably and we used it for our own purposes such as measuring periods between historical events. Time as a dimension might have been there all along, waiting to be discovered.
