The Door to Earth is a Door in the Afterlife leading to Earth. It is guarded by Jeff, the Doorman. The door can be accessed using The Key, which Jeff gives to Michael while he's escaping from Gen.
Use[]
The Door appears to allow Immortal Beings to visit Earth; it is unclear whether human essences travel through the Door routinely after they die, although presumably there is a nearby entrance also located on The Bridge. The Door appears to lead to other locations without the use of The Key, as Jeff visits Michael in The Good Place in Chapter 37.
