He never met his parents. That's why. That is if you accept the Bardock movie as canon instead of Dragonball Minus. If you accept that as canon, then he was still a baby back then and most people (imo) don't retain a lot of their memories from when they were infants.

That is because Goku forgot about his parents. And btw the Dragon Balls can resurrect a person who was dead for 1yr. But Bardock and Gine were dead past 1yr means they can't be brought back.
BardockGineGoku/ParentsGoku's father, Bardock, and mother, Gine, were both Saiyans from Planet Vegeta. While his birth name is Kakarot, Goku was born from the relationship between Bardock, a Saiyan who was considered one of the bravest warriors on the planet, and Gine, a humble Saiyan.
Gine is presumed to be killed along with most of the other Saiyans when Frieza destroys Planet Vegeta. No account details her survival.
