I don't really think it would be that surprising, if shown to be possible. Imagine you were zoomed into the future and saw technology that teleported you from one place to another for instance, or a single harmless pebble that could provide basically infinite energy remotely, or really basically anything. There's no remotely viable way we know of such things being possible, but if it turned out to be possible, it'd mostly just be a curiosity of how it worked. If somebody tried to convince you it was magic, you'd eyeroll. The greatest discovery might be to find that some sort of magic is real, but good luck convincing somebody of that!

Read ancient texts and they were largely like us, sometimes to a shockingly large degree when considering some aspects of the past, and in many different parts of the world. So I see no reason to think that it'd be fundamentally different for somebody from one of those eras.
