I do understand now...No, that's what we're saying. Trying to use AGE 737 makes Jaco not fit, and using AGE 739 make a decent amount of other stuff not fit. Jaco can't take place in AGE 737. It has to be AGE 739 and Goku has to be two years old, because the manga is stated to take place ~10 years before Dragon Ball and Bluma's age in Jaco fits in with her official birth year. So, Toriyama has now decided on a specific year for the destruction of planet Vegeta in his own manga continuity.
Also, both Goku's armor and Gohan are scuffed up from their brawl, meaning it was on him when they fought. None of the house seems to be wrecked though (besides a plate), so it didn't happen indoors. In all likelihood, Goku exited the pod himself, fully clothed, and went on to attack Son Gohan. After defeating the boy, he dragged him to the house for food and offered him a home.
So if we go that Jaco tha Galactic Partolman is intirely canon as having that creator solely Toriyama, the history of Dragon Ball might change like this:
Age 637: Goku is born, but not sent immediately to Earth
Age 638 or Age 639: Goku was sent to Earth, Beerus fell asleep, Bardock had somehow (completely unknown how he got into the situation) the "fight" to stop Freeza, but killed or sent in the distant past.
Age 639: The earlier events of Jaco manga took place. Goku arrived on Earth, had the fight against Son Gohan, and being "adopted" by him.
Age 649: The Jaco manga's later events took place and Goku was about to meet Bulma for the first time.
Age 673: The Majin Buu saga took place
Age 675: Bulma and all the heroes(save for Vegeta) somehow met Tarlbe for the first time.
Age 678: The events of Battle of Gods movie took place, but Bulma's age wasn't correct, as she should be sould be right 45 years right on that day.
Age 678 or 679: Pan was born
Age 679 or 680: Bra was born
