there are contradictions like Luke Mother
It’s not a contradiction. Check out this video: https://youtu.be/7qH8m_zXRRg
Timothy Zahn Version of the Clone Wars
It’s not a contradiction. All the discrepancies between the Thrawn Trilogy and the Prequels have been explained by the pre-Disney Lucasfilm years ago. When Pellaeon talks about him remembering fighting Clones during the Clone Wars, he’s talking about the Battle of Seleucami from the Republic comics by Dark Horse. In the Seleucami arc, we see that the Separatist are trying to create an Army of Clones to fight the Republic, and that’s exactly what Pellaeon is referring to in the Thrawn Trilogy. Besides, when it’s stated that the Clones were the bad guys in the Thrawn Trilogy, they’re still talking about the Battle of Seleucami. So yeah, it’s not a contradiction. Sure, you can say that it’s a bit convoluted, but it’s not a total contradiction. The Thrawn Trilogy directly contradicts TCW, because in the show there’s no Battle of Seleucami and there are no Separatist Clones. But it doesn’t contradict the Clone Wars Multimedia Project and the Republic comics.
Sith becoming Force Ghosts
It’s not a contradiction with the Prequels. Sure, George Lucas stated that the Sith can’t become Force ghosts, but there’s nothing in the Prequels that suggests that. So no, it’s not a direct contradiction with the Prequel Trilogy.
Palpatine Resurrection the Prophecy of the Chosen One did not exist
You can come up with a billion possible explanations that can make the Chosen One Prophecy fit with Palpatine’s resurrection in Dark Empire. So no, it’s not a direct contradiction with the Prequels.
before 1999, Luke Jedi Order letting his Jedi get Married seems like this was something Normal with the Jedi before Lucas Prequels, Corellian Jedi,
Just because the Jedi had rules that forbade marriage in the Prequels doesn’t mean those rules always existed in the past and will always exist in the future. So no, it’s not a contradiction with the Prequels.
in Old Video Games like Dark Forces 1 and 2 or Shadows of the Empire the Empire seems to have ruled the Galaxy for more than 19 Years it doesnt look like the Prequels took place in the same Universe as those Games,
This is a purely subjective feeling, and it is not proof of any objective contradiction. Besides, in Shadows of the Empire, the Empire has been in control of the Galaxy for 25 years, not 19 years.
looks like Ashka Boda could have been the Leader of the Jedi Order before the Lucas Prequels and not Yoda or Mace Windu
Again, just because the Jedi had more rigid rules in the Prequels doesn’t mean they always had those rules. So again, it’s not a contradiction with the EU.
