>they stole it
First of all, that has never been said in canon, second, even if they stole it you don't keep that stuff for generations without keeping knowledge. You don't get THIS unless your people keep traditions, knowledge, wisdom and information from the older generations, it's impossible.
You sound like the kind of idiot who thinks vikings were a bunch of drunk brutes who just fought and raped like rabid animals.
Also the think Goku and Vegeta learned wasn't even martial arts, it was a reminder of a saiyan's proper mindset.
