Technically not the most accurate analogy but this may help you visualise it a bit easier (please add any other details if you have any corrections or to clarify better).
If you’re familiar with audio waveforms -like shown on Soundcloud for example- start a song, watch the cursor move as the song progresses and pause it at any point. The waveform takes different shapes as the song progresses and the exact shape when you pause it at a specific time shows you what’s happening in that exact moment. It changes over time as there’s different stuff going on. Now go back to the beginning of the song. There’s no waveform before the song starts because there’s nothing there right?
Time is just what we use to determine what’s going on in a certain instance. As far as we know there was nothing going on before the big bang so there’s no time.
