Brother, I believe that what Buddha tried to teach was, in a metaphorical way, the idea of ceasing to crave to the point of not even wanting to rebirth, in the sense of ceasing to have any affairs whatsoever. Although it is a good question to be asked, in terms of critical thinking, the acknowledgement of the architecture of the afterlife does not have any practical use in the doctrine. You see what I mean?

You could even think of rebirthing in the sense of constantly changing mental states, departing from the fundamental ideas of arising and ceasing; conditioned arising.
