Well Entry Number 17's room name is room_gaster, implying that Gaster wrote Entry #17. Since all know skeletons speak in unique fonts which are the same as their names, it is further implied that Gaster is a skeleton. Through datamining it's revealed that Gasters stats are all sixes, and 66 is the fun value needed for Mysteryman. But there still isn't any evidence saying that Gaster is specifically Sans and Papyrus's dad.
