We don't know. We can go back to within nanoseconds of the Big Bang, around 14.6 billion years ago, but that event makes it impossible to go further. It may be that time only began then - which is why we can't back further, because there is nothing to go to - or it may be that time does go back well beyond that. Whether to only a couple of weeks, or another 20 trillion years, or for an infinite time, is up to what you think.Or possibly a loop in time,Where future and past come together.

Did they go to school in the iron age?
Schools have existed at least as far back as the bronze age...prior to the iron age. But there is little similarity between those early schools and the ones we have today. Back then, education was available only to wealthy families who didn't need to labor in the fields to survive, and schools were very few and far between.
