What i think is that Sans never met Gaster and Gaster never met Sans. So Gaster is not his father cause his sprite doesn't look like a skeleton. I'm with ya, I don't think Gaster is Sans/Papyrus father. I actually made a theory about it.

Now I know it's not the best but I did my best pointing out some stuff I found. Please comment what's good and what's bad about the theory. The more criticism the more I can learn and expand.
