2,,4,,6,,8, come on folks let's speculate.
Such an idea has been thrown around in the past. It is probably based on following the concept that God was once like us and has progressed. If that is true , then progressing to get a place to create spirits and place mortals is not a huge jump in logic. That said , it is pure speculation without firm scriptural backing. Broad scripture interpretation of statements like we will inherit ALL the God has, can lead to such thinking. Personally, I have a tall shelf set aside for these kinds of ideas.
