@Amazing hence kerb Obviously you can't communicate with someone when you use comparisons that make zero sense. A person "living 50 years ago" has not experienced anything out of the ordinary. They have lived in the 1970s and have experienced everything that the 1970s had to offer. They would have no direct knowledge of flying cars or anything advanced-adjacent.
MC on the other hand HAS expierenced things out of the ordinary. He was transported to another world through a big gate. Interacted with a sentient shadow for 200 chapters. Understood that different races like elves exist. And whatever other supernatural things that he has directed seen that I'm not remembering withing the last 200 chapters. Your comparison has zero relevance to the MC. MC has seen supernatural already. That's why it makes no sense for him to need to convince himself of yet another supernatural thing, while being in an entirely different world from his own.
