Saiyans are just cartoon versions of monkey demons. Monkey demons are a monkey species derivative of nephilim, which were produced by intermixing monkey, angel, and human dna. The saiyan race is symbolic for the monkey demon race that thrived during the Pre Flood era of human history. It was eradicated in a global world war and the remnants were killed off through a global food. Afterwards throughout history human militaries have eradicated any monkey demons that were born within human and / or nephilim societies.
The spirits of monkey demons exist in the 4th dimension either on earth or in hell. The spirits of the monkey demons whose physical bodies were killed during the PreFlood era were crushed in battle against God’s race of celestial dragons. These dragon celestials forced 9/10ths of the monkey demon race to live in hell where they reside as one of many species of demon tormentors of human souls. 1/10th of the monkey demon spirits reside on earth - these are the ones that are behind Dragon Ball, King Kong, Monkey King, and monkey demon anime derivatives.
In Dragon Ball the ultimate gods of the show are the celestial dragons. They’re symbolic for the celestial dragon race who are the fore fathers of the nephilim race which sired the monkey demon race. Just look at the title of the show - Dragon Ball not Monkey Ball even though monkey demons are the main characters of the show. The title of the show signifies the celestial dragon princes that rule over the monkey demon race, whom the monkey demon race is completely dominated.
