Order 66

Order 66 happens in STAR WARS episode 3. It is the time when Palpatine kills four Jedi that try to kill him. Order 66 is the only order that clones say."Execute Order 66"! Every clone says that. That is a bad word like kill. And somebody made that thing up and it is horrible! Who made that up??! And why did that happen? Are Clones insane?! Why does it have to mean to kill a Jedi? How long did they execute Order 66?
Jedis are very powerful, they can use the force to move stuff and sense dangers, they can destroy pretty much everything, with a lightsaber And once I saw Yoda kill clone commander Gree. By 'cuttin off his head with his lightsaber.  By then I mean it! Usually Jedi are unstoppable but they did not know that clones betrayed them. So clones ambushed  Jedi by shooting them on the backs.
Clones are insane maybe. Or senile. And a clone once killed Krell. Most Jedi were killed in order 66 but two Jedi survived, Obi wan ken obi and master Yoda. Then Luke Skywalker was born and together they fought the  empire and destroyed the death star. And the Sith were defeated. But a Sith might  born one day. And a new battle will start.
