He calls him G and stuff, Gaster is more like a close childhood friend or something. Aside from that, if you actually thought over your theory, Sans and Papyrus might not even know Gaster's his father.

Euh what??Sans is never shown calling Gaster "G"in canon only in fanfiction.But in canon they DO have a relationship because

1.Sans has blasters called "gaster blasters"which strongly connect him with gaster

2.Sans has a machine with blueprints written in"weird symbols"and gaster coincidentaly wrote his entries in "weird symbols"aka wing dings

3.Gaster ,Sans and Papyrus are by far the only characters that speaks in a special front,making sans and papyrus connection even stronger

4.Sans says a similar line to one of the Gaster's followers"its rude to talk about someone who's listening"in Undertale official tumblr

5.Toby Fox himself mentioned that Sans and Papyrus had another redacted relative and since gaster IS redacted from the game and talk in a special front just like the brothers and that Sans has blasters called "gaster blasters"and that Papyrus says that he will "blaster you",that all implies that Gaster is this mysterious redacted relative.

They seem to have a connection in the game but i dont view Gaster as the brothers'father(even though thats a very popular headcanon) because i think this role does not fit the personality he show in the game.If the "you two"in the entry number 17 are Papyrus and sans then its unlikely that Gaster is their father since no parent would make their children participate in such weird and dangerous experiments or ask their children what they think about their experiments.And if Gaster was really their father,who would be the mother?I mean if Toby intented to make Gaster Sans and Papyrus father ,there would no reason for him to not reveal the mother's identity.So i rather think that Gaster is Sans and Papyrus's another brother and Sans is the oldest one,which would increase Sans's guilt regarding Gaster 's disappearance and make him more dramatic.I also think that Sans cared deeply about Gaster(and that this brotherly love was mutual),which is why he tried so hard to save him by fixing the machine Gaster fell in,but failed which is why he fell into depression and consider that all the efforts are worthless in life which turned him into him the lazybone we all love (and used the resets as a"poor excuse "to never do anything).
