I mean, the shopkeeper in Snowdin reveals that Sans and Papyrus just "showed up one day and asserted themselves." 

What if they both arrived in the Underground, were killed, then Dr. Gaster brought them back to life as part of his experiments? 

Dr. Gaster takes the bodies of two brothers that fell down and brings them back to life to help him with his experiments. The two have no memories of their previous lives, but have remnants of their personalities with them still. Sans being laid-back, friendly, yet extremely intelligent and fiercely dogmatic. Papyrus being outgoing, full of energy, but analytical and detail oriented. 

I find myself thinking of the items you find laying around the underground, for example the tutu, the frying pan...maybe Papyrus was a cook, and Sans was whoever owned the notebook and glasses? I'm not sure about that one. 

So once Sans and Papyrus are created, they work for Dr. Gaster. He becomes like a father to them and a great mentor to Sans, who is clearly interested in physics and that kind of thing. Later on, Dr. Gaster creates The Core...it malfunctions, he falls into it, is wiped from time and space, but nobody remembers him but Sans. Papyrus somehow doesn't remember anything before the Core malfunctioning. So, Sans and Papyrus have no choice but to move to Snowdin. Sans builds a machine of his own to try and go back in time to save EVERYONE...but it fails, and now sits under a curtain in his workshop collecting dust. 

As time passes and more resets occur, not only does Sans have to live with the immense uncertainty and unpredictability of whether or not he'll watch his brother die, whether or not everyone will die or go free, etc, the memories of his beloved mentor, Dr. Gaster, begin to fade away. 

So he draws a picture from memory, the best he can, of himself, Papyrus, and Dr. Gaster and makes a note, "don't forget."

Anyway, onto the relation of them being humans...

They are humanoid-looking skeletons. Yes, even for a cartoon, they each resemble a HUMAN skeleton. This theory can be supported by when in the Genocide route, when the player strikes at Sans, there is a red gash on his abdomen and is bleeding from the mouth. 

Now, now...I hate the theory that "OH IT'S A SKELETON MASK AND THERE'S A HUMAN BEHIND IT!!" No no no. Where does blood come from? Where is it made? Bone marrow. It would be perfectly logical if a bone was broken for it to bleed. Pretty simple, but a huge piece of evidence that Sans and Papyrus could, really, be humans. 

And how funny would it be for Papyrus, being such a "huge human-hunting fanatic," to be a human himself? Oh the irony!!

WARNING!  THIS PAGE CONTAINS SPOILS!! READ AT YOUR OWN RISK!!!

If you look at picture of W.D. Gaster, you will see him with a black lab coat, his hands popping out, and two cracks in his skull.  But if you look at a picture of him when you try to interact with him in the game, he will make a face with extended eyes extended up and a huge smile across his face.  To see Gaster and his followers, you'll need to mess with the game and set the fun level to 66.00.  Now, on Tuesday of October 18, I searched up a picture of Gaster sprite, and next to his original sprite is a picture of when you try to interact with him.  Now, I decided to glance at this picture and i saw that he was making the wingdings signs F and H, ☞ ☟.  Now it's very slight, but you'll be able to see it.  Now, seems like there's a reason behind this, doesn't there?  I new that it wasn't just there to be there, and I new that there HAD to be a reason behind it.  So I did the natural thing, and went to my best friend, Colton.  Now, I explained my suspicion of Gaster's sign.  Now, naturally, he made a joke of it and told me that he thought that it meant Fuck Humans.  Now, it kept nagging at me in the back of my head, and I wanted SO MUCH to find out what it meant.  And then, it happened.  Colton came up with it, figured it out.  Now, let me explain.  Have you ever heard of the Mirror Effect?  If not, then let me explain.  The mirage effect says that if you are facing something from the front, then it's like looking in a mirror.  Say that you and your friend are talking, and you're standing in front of one another.  His/her left would be your right.  That's the mirage effect.  Now, apply that to a video game.  Instead of W.D. Gaster signing F H, he was signing H F.  But still, what could it mean?  Well, what if it meant Help Free? Help Free?  That still doesn't make sense.  Yes it does.  Help free HIM.  Help him get free.  Free him from his prison.  Now, what prison?  Who would want to imprison Gaster?  No one.  There is a theory out there, and evidence, that Gaster's own 'creation' that he fell into, is a rip in space and time. 

Sorry for the long theory, but it is worth it.

-My theory on the mysterious WD Gaster-

          During this paper I will explain some things, and bring up some other questions. Firstly is how can WD be found when he isn’t in the game no matter how hard anybody searches, he is in the game but in order to find him and his friends you must edit the code of the game. Upon editing the code, WD and his minions will be found in the CORE which is where WD worked and created some machines. To find WD himself you must go to a room in an area of the underground called waterfall, upon trying to talk to him he will render no speech, if you get too close he will act surprised and disappear. When you see him speak he uses his form of “sign language” which is known as WingDing. When the font is capitalized you can see that the first part of the alphabet is made of hands. If you notice the initials for WingDing is WD, such as WD Gaster, which is the font he speaks. There are only two other characters in the game that use a font that is their name. These characters being the skeleton brothers Papyrus and Sans, both of these characters speak in the font they are named after. This leads me to believe the skeleton brothers are related to WD, possibly cousins, siblings, or WD could be their father. WD did live with them for some time as proven by his doctor’s badge, his blueprints (written in wingding) and WD’s broken machine, as well as the pictures of the uncorrupted science team including WD and Sans, inside a room of the brother’s house. I believe the machine was meant to analyze and change timelines, as proven by Sans’ quote : “our reports showed a massive anomaly, timelines jumping left and right. stopping and starting…” .

If you notice, Sans says “our”, which indicates he worked with someone who was analyzing and working with timelines: WD. I believe that part of this machine was able to send someone into a specific part of a timeline, and allow them to change it. This would explain that if WD’s entire science team was with him watching this experiment, and only two of them (one being WD the other being Sans) contained the ability to protect themselves with a shield made up of the magical component they controlled (Sans controls bones, WD controls magic hands that can float and do multiple effects including shield).  Keep in mind the only people that would be able to understand WD’s font would be those related or used to his language, the only people who knew him such as leaving Sans and WD’s science team. This means that whenever WD made an attempt to change the anomaly that was impending, something could have messed up in the machine which caused a malfunction and thus vaporizing most of the team and WD himself, but since WD would have protected himself and his team, instead of them dying, they were torn apart and left in tiny living bits of their souls in the code of the game excepting Sans who would have guarded himself and been unaffected. Due to only Sans and the science team knowing about WD, this would have meant that after this event only Sans would be the living person knowing of WD’s existence. When I say game code I mean game code, only few people in the game undertale can warp this code to do strange things, such as Sans warping the code to make his shortcuts, and the main character being able to reset themselves, as well as Flowey the flower being able to change this code and know of the changes that happen in the game when it is reset, closed, or saved by the person playing the game.

          The only way to find the souls or bits of souls of each of the science team is by editing code, as stated before. It actually makes sense if you think about it; WD and his team were ripped to little pieces and scattered amongst the code, thus why you only see them if the code is disturbed, it awakens them to tell the tale of WD. This probably has you thinking; “Why would they create a machine for timeline analysis and manipulation.” That’s an answer that is easy but hard to give, Sans actually accuses the main character you play as in undertale to being the anomaly, when he is actually quite wrong. If you ever wondered when you play as the main character and the game has a form of realism and logic; why do you get messages that say “….This fills you with DETERMINATION.” That is not your conscience, that is the anomaly, the only other person to manipulate time, the only other person to be seen after death and be able to speak to you in your mind while narrating your actions in-game: Chara. The first fallen child, the child who befriended Flowey, and killed themselves to empower him to pass the barrier, Chara is the anomaly. She is the reason the timelines jumped left and right, she is the reason WD died attempting to find the problem, she was killed as a human with the power of time manipulation, thus why she can speak to you when you fall. She is the reason for all the grief of the underground, because of the power seen in the young prince before he became Flowey, the next children to fall were killed, thus causing the queen to leave and hide within the ruins. It was all because of Chara.

I don't know if this easter egg has already been found because it's actually quite straightforward in the game and easy to notice.

In the Pacifist Route we get a glimpse of the Genocide Route. In the Pacifist Route in the True Lab one of the tapes has Asriel telling Chara that it's not a good idea. Same exact set of words appear nearing the end of Genocide. What if the tape in the True Lab was not meant to be a flashback but instead showing glimpses of another timeline (aka, Genocide).
