I noticed that too. It could be a plot hole, because one and only witnesses with ability to cross the Barrier - Chara and Asriel - have "died" right after they returned from Surface. They have no time to tell anything to anyone. Except six humans - if they have been living in that village, then they could have seen entire incident with Asriel. And after they get to Underground, they told whole story to Asgore, maybe.
