There’s a lot of tangles in what was implied from the original trilogy.

“You fought in the clone wars?”
That felt like a throw away line, but I assumed that there was were multiple wars involving clones. Like The Punic Wars. I also assumed that Obi-wan had had a long Jedi career, that involved him being involved in possibly multiple wars.

“I haven’t been called Obi-Wan since before you were born.”
This gives the film a nice past, as if so much had happened PRIOR to ANH. But it doesn’t make sense if you think about it. It’s assumed that Luke was conceived while Anakin was still good, and that means that Anakin hadn’t yet turned to the Dark Side, joined the Emperor and help establish the Empire.

“Powerful Jedi was he, powerful Jedi.”
It makes it sound like Anakin was this super powerful Jedi, but prior to his fall, we didn’t see him do anything that average Jedi couldn’t do.

“When I met you father, he was the best pilot in the galaxy.”
Anakin clearly had a different career prior to becoming a Jedi.

“You father’s lightsaber…he wanted you to have it.”
This implies that Anakin either knew he was going to have a kid, or that Luke was already born when he said that.
