Why Papyrus though? Sans it's pretty clear about, because all the hints, but Papyrus don't say or hint anything about timetraveling, reseting, saving or even science itself! Is it only because he's the brother of Sans? Btw, undertale is all about timelines, in other words: multiple alternative realities. What we know though is that Frisk has the ability to change timelines, an ability Sans does not have.

Also, the only way you can get the picture of Frisk, Sans and all the friends in the album is by already completing pacifist at least one time. So it's a picture of that past reality, not some unknown one
