This was just i gain by reading other blogs and websites so here's the History of One Piece and Monkey D. Luffy and his Family of "D"
Once there was a Kingdom on the moon that had advance science Beerka.
The people of Beerka could technology and its name was that they use in skypia). However,
make robots and dials (the things because they ran out of resources. They migrate to the blue planet (the blue planet is earth, and if in it when he goes to the moon, you see the comic cuts with ''Enel'' you can see writings that say people of Beerka migrated to the migrate is probably the one that blue planet because of lack of resources.) the ship schematic that the people of Beerka used to tom (Franky's dad) had. when the developed into a huge Kingdom. People from the moon (Beerka) came down to earth, they accepted
everyone to join and use their technology in peace and soon however, a secret organization the weapons are named the wanted to take the power and authority of the Beerka for themselves and started a war.

- So the Beerka developed three ancient weapons to win the war. Shirahoshi'' her ability to summon ''Pluton'', ''Poseidon'' and ''Uranus''. Pluton runs underneath the ocean floor to change the tides of the sea to make a shied against enemy ships. ''Poseidon'' ''Princess nothing else is known about it. ''Sea Kings''. Like Pluton and Poseidon, Uranus is a dangerous weapon which can be used to rule the world or, in the wrong hands,
destroy it. But as of yet, absolutely It was first mentioned during Nico undersea volcano eruptions and Robin's conversation with King Neptune, when she says there are
three ancient weapons that bear the names of 'gods'.

Later on traces of Pluton's drilling underground builds up due to becomes the "Red Line". and the solid form of sea water furthermore, The ''Calm Belt'' and the ''Grand Line are formed which divided the ocean into four. Poseidon is a cannon made from fairy bass (sand from the moon). The sand from the moon has a tendency of coagulating sea water these extraordinary weapons, the made from the moon sand was used as the cannon ball. Later on, the cannon balls that were used during the war sank into the ocean floor and became ores called ''Sea stones'' (the stones that devil fruit users are weak against). Even with organization and take the shape of people from the moon lose the war after 100 years of fighting. they conceal the three weapons (Pluton, Poseidon and Uranus) so the secret
organization can't use it for themselves

- The survivors of the people of the moon hide away from the secret
1. they erase the 100 years of the half moon ''D'' to use as their middle name. (this explains people with ''D'' named) the secret organization that betrayed and destroyed the people of the moon name themselves "World Government" and started a project to hide their wrongdoings.
----their offspring are treated like history of the war. (the 100 years of history (the void century) that robin wants to find)
2. They send 20 soldiers to the moon to erase any trace or evidence of the people of the moon. (the 20 soldiers that were sent to the moon are later called world nobles and won't find them. One Piece is in kings. this also explains why world nobles always wear space suits.)

- The survivors of the people of the moon make a small Island called ''Raftel'' which Gol D. Roger reveals it to Edward Newgate while they drink. The survivors hide in Raftel
so that the secret organization 100 years of history) and placed it this island and ''Gol D. Roger'' was the only person to find the island. The reason that the ''D'' people are
not on the island, is because the people of the moon wanted the world to know the evil deeds done by the government. They made poneglyphs (bits and parts of the
all around the world and sent out a - The Beerka's (people of the moon) selected number of their own people (D's) to find it and let the world know the truth. They call it
''The Will Of D''

The people of Ohara were the last people who could read the ''poneglyphs'', but they were all killed by the world government. There were only one child who survived, her name was ''Nico Robin''. will bring the four sea's in to one, make one final secret weapon while
they are on the island of Raftel. This ancient weapon's ability is to take the four seperate seas that were divided by Pluton, and turn it back in to one huge ocean (AKA ALL
BLUE (the ocean sanji always dreams of). because of its ability to turn the world upside down, which that weapon is called "ONE PIECE". Therefore, he decided to create The
800 years has passed, a pirate named Roger successfully reach Raftel and discovered the true history. He knows exactly what to do, but unfortunately his body didn’t allow him to… he had this incurable disease, remember? whereas the project needs a lot of power and time to complete, 2 things that Roger didn’t have time. Golden Age of Piracy instead, hoping that there will appear massage in his place. someone who is strong and righteous enough to complete the massage in his place.
