[Star Wars] If there were other "Jedi" or people with the potential to become force users, why did Yoda and Ben think Luke was the only one left?

"That boy is our last hope."

EDIT: I actually forgot that Yoda knew about Leia being Force sensitive, either way my question is the same.

EDIT 2: I think my question is getting *sort* of confused. Besides Luke, and somewhat Kanan were there any other fully trained Jedi still alive that could have helped Luke with training besides Ben.

The Force was probably sending out very strong "don't screw this up" signals to both Obi-Wan and Yoda with regards to Luke and his training.

After all, Luke *was* the best option for clearing out the taint of the Dark Side from the galaxy, because - ultimately - it was his relationship with his father that had the greatest effect, and not his relationship with the Force.
