Can someone explain to me why there are actual people just deny Gaster’s existence?

It legit does not take that much effort to know that he is in Deltarune and will likely be relevant to the story. It just legitimately doesn’t make any sense to me. I just cannot wrap my head around it onto why people don’t believe GASTER isn’t going to be in Deltarune or believe he just doesn’t exist.
