I'm gonna sound like an 18 year old dude taking a first philosophy class, and I do not have my thoughts on this fully worked out by any means, but I truly believe we view the world through a filter, and that filter is socially constructed. Other people can see things that I can't see. Those things I can't see are magic.

Edit: This is largely based on me reading people's accounts of a specific traumatic event where the victims were from a very different culture than the perpetrators. The perception between cultural groups of what was physically happening (and possible) was wildly different and the events were literally shaped by what people were/were not able to see right in front of them.
