You are missing what should be obvious: God is perfect...and is spirit.Traditional Christian consensus is actually rather vague about the afterlife, and anything beyond that little bit is speculation.
The resurrection of the dead is about continuity with this world, that in fact, this life matters (and thus making sin all the more tragic). As biblical scholar N.T. Wright has in the past few decades pointed out, the biblical hope common to many Jews and Christians is for a renewed creation where things are set right, not for an otherworldly existence.
Now, why would some Christians focus instead on "this world is not my home?" I suppose it is due to certain gnostic tendencies in some strains of Protestantism, to deny or ignore the physicality of God's incarnation in Jesus Christ implicitly. The incarnation as theology is not necessarily central to all self-described Christians, and as a consequence, the resurrection takes on a decidedly different emphasis.
The manifestation of this world, is not to devolve God to be physical, but to set men free from it.
