The series has literal space wizards.
I get the fandom urge to know more. But with Star Wars the tendency to connect and explain everything is a fair bit of the reason the prequels are so eeeeeeehhhhhh and the old EU was so redonkulous.
I mean that’s how you get midichlorians.
So I’m not putting much stock in the time travel and clone talk, which is pretty much all over the place. To the point where I’ve seen people online attacking JJ Abrams for the clone stuff, despite that being a fan theory with no connection to the guy. These things are speculation from particular types of fans more rooted in their own preferences than anything in the films or extended material themselves. They started before TFA came out, and mostly before anything was known about it. And as each entry comes out, and doesn’t work with the theory, the theory changes to somehow still be valid.
Abrams does love him some poorly conceived time travel though.
