>>52474528>The plates were made with technology too advanced for the time, that's explicitly statedNot exactly. The book states that determining anything about the plate is beyond modern science, not that it was made with more advanced technology. We don't know how the plates were made, they could be similar to Arceus' plates and were made by a Pokemon rather than technology, for example. Not saying Arceus made the plate, just that another Pokemon could have. It's not necessarily technology or humans that made them, we don't even know what they're made of beyond a seemingly indestructible metal.
