I've been playing Undertale for a pretty long time now...

But I still don't know who is the older brother...

Sans or Papyrus?

Many comics have said that Sans is the older brother...

But I haven't gotten any proof yet.

It makes sense that Sans could be the older brother...

But it makes just as much sense that Papyrus could be the older brother.

So could someone please tell me who is older,

And if possible, clarify it with some reasonable proof?
