Sans specifies that he considers The Surface and His Home to be two seperate things. Sans is not from the 'world' above. He's from a different world.

Toriel, an immortal, is old enough to remember what the Surface World is like, with its own brand of humanity. Her ex-husband Asgore was King of the Monsters during the War, and named their first towns in the Underground after the Barrier was cast. Toriel can tell that young Alphys has some misconceptions about what the humans above are really like, and that the anime she's reading is not an accurate historial record.

We get a look at what The Town Just Outside The Barrier looks like in Deltarune, and it's a perfectly normal human village by our Real World standards, with no anime supertechnology to be found. This is the town that Chara was from, the one she ran away from.

But somehow, the Underground itself, despite being reduced to reverse-engineering surface world garbage to gain most of their technology, acquired the power to make anime wonders like dimensional portals, cell phone jetpacks, and sentient transforming robots that actually worked. They did NOT get this technology from Chara's surface world, because it doesn't exist up there.

The only explaination for these other-worldly-wonders is the Legendary Royal Scientist Wingding Gaster, who designed The Core, a Mad Scientist lair that literally looks like it came from another universe completely alien from Rustic Snowdin.

Wingding Gaster didn't come from Chara's Surface World, any more than Sans did.

The Man Who Speaks In Hands is, indeed, The Man From The Other World. And since Sans is our friend, Sans isn't the one the Riverperson is telling us to Beware.

I've given my Scanning Tunneling Microscope account of all the points of data I've found that point to Sans being a human above.

And if you disagree with my conclusions, all you have to do is find some counter-evidence that I can't break.

But everything I see says that the Riverperson was indeed referring to A Human From Another World. Because every indicator I've found says that Gaster must have been a human also.

Which means we have two humans, who clearly met and knew each other, that both traveled from a different universt to this one, to research The Time Anomaly.

As Sans said, he didn't travel alone. And he wasn't the one who made The Silver Key Machine, because he can't fix it.

So no... The Surface World isn't the same thing as The Other World.
