For the sake of the argument, you get to arrive up to 24 hours before the event starts and leave up to 24 hours after it ends.

Either watch the building of the Tomb of Tutankhamun. Watch and record what happens. I can’t interact or interfere (which mean I would have zero effect on the time line), but I would have video evidence of how they did it. Since it took years to build (supposedly) we don’t really know how long it took, I would watch the beginning week or two of it.
Be a hell of a shock if it really was “aliens”. lol
