Just because the timeline of Frisk/Sans' journey before Undertale isn't mapped. doesn't mean the theory's debunked.

Somehow, Sans knew in advance of Frisk's arrival, and his exact appearance when he arrived.

Remember that The Convienent Lamp, twice given that name by both Sans, and the save point on the next page that reminds us of just how convience that lamp was, was unplugged, sitting in the middle of a field, seemingly useless.

And it wasn't even neccessary to fend off Papyrus, because when No Mercy Frisk refuses to use it, Papyrus just walks away anyway without taking notice of him.

If Sans is as lazy as he claims, he could have just put a cardboard box there, if the purpose was really to give Frisk somewhere to hide. Instead.. he custom fashioned the lamp into a design that was a pixel-perfect match to Frisk's own silhouette. Something Sans was aware of even before Frisk went behind it.

Sans and Frisk are both leff-handed. And it's revealed in the Sans boss fight that Frisk is also a powerful PSI wielder, able to teleport out of deathtraps Sans sets for him after "The Real Battle Begins" with the very same sound Sans uses when he teleports himself.

And if it weren't for Sans' baggy costume, he'd be exactly the same size and shape as Frisk. Viewed from the back at the Grillby's dinner, both have the very same cartoonish slender neck.

I've listed the ten or so reasons why Sans must be a human in my script.

Sans not only shares pre-knowledge of Frisk's journey, but several characteristics that are both rare, and ultra-rare for humans

And while six humans have already taken the Underground journey, and died on Sans' watch, for some reason Sans won't fight Frisk unless Frisk is 100% evil and such a fight is inevitable to save the timeline.

Sans has already killed Flowey multiple times in other timeliness... just for talking to Papyrus funny. Yet Sans, who clearly knows everything Frisk has done with his friendship with Alphys and her camera network, takes no action even when he sees Frisk kill Papyrus.

And for some reason, Sans put the key to his room, and his greatest secrets, on Frisk's keychain on the phone that Toriel gives him.

Sans and Frisk share a powerful, special link. Which is why I believe they must not only both be humans, but the SAME human from different times. Something that should be impossible without time travel alterning the timeline.

This is why I call Frisk "Beta Sans". He's taking the same journey that Sans himself took in the original Alpha timeline, which is how Sans knows when Frisk will be arriving and what he'll look like. And why he's secretly doing so much to help Frisk, despite Asgore's orders to kill all humans.

Undertale exists in an altered timeline. In the original Alpha timeline Gaster didn't die in 201X, but survived and stayed on as Royal Scientist to create his own time-lost version of True Lab Entry 17 which mirrors Alphy's own co-existing entry.

This is why I call Undertale the Beta Timeline. Gaster's Darkest Experiment did something terrible that Sans traveled to the past to try and undo, hoping to give his earlier self a better chance at a better ending.

Is it really just the "Beta" timeline, and not he Gamma or Delta timeline? That's less certain. But if time has been repeatedly altered in the same place you'd think a horde of Sanses would begin to appear, instead of just two. And tracking two parralel timelines through fant echos in spacetime is problematic enough.

So, even if we aren't aware of this part of the story, or how this came to be, I do think Frisk is walking the same path that Sans himself walked earlier.
