The mistake most people make is that they seem to think that Midi-chlorians are the force, but they are not. Midi-chlorians are not the force! They are simply the vehicles that help life forms feel the force. Qui-Gon explains that without the Midi-chlorians we would have no knowledge of the force, not that the force would not exist. What we see as "Magic" is only science that we don't understand. We saw the force as magic in the OT and then once it was explained a tiny bit it didn't quite feel so magical anymore. I get that, however, Qui-Gon basically just says that we can feel the force by interacting with organisms in our cells. To me it's still pretty magical, because how that happens is still a mystery. Obi-Wan explained it as "an energy field created by all living things." The energy field is created by life forms communicating to each other using the Midi-chlorians within them.
