No offense meant, but how exactly is it difficult to decipher? The Jedi believe that the Sith have been extinct for 1000. After Qui-Gon has a run-in with an extremely-Force sensitive boy and a warrior trained in the Jedi arts, though, he begins to suspect this may be a child of prophecy and that the Sith have returned. The Jedi are obviously skeptical about this given that they've believed the Sith were extinct. By the end of TPM, though, they're convinced that the Sith have indeed returned and thus Anakin may be the Chosen One Qui-Gon suggested. I guess I'm not seeing how this is complex. The characters' positions are pretty clearly laid out.
