This question has been bothering me for a while,I can't come up with a logical explanation heres both of my theries. Theory 1.Souls are born thru human beings and other animals,everybody creates souls,I don't know how often,but everybody does it.I guess once you hit puberty you get soul making abilities,cause with overy overworld theres a underworld right!!Souls are then transfered into new born babies when fertilization of the egg begins.The physical aspects of the child are of course are present and represented physically,but the mental and spiritual(sub consious) shows characteristics of the donor host or maker,therefore good and evil people make more good or evil people. Theory 2. Souls are reincarnated from the afterlife,no souls ever die,the cycle never ends.... Both of these theories do not involve a god-like entity,not saying she does'nt exist,but that mofo has better things to do,therefore saying that we control our own planets.If we let bad or corrupt souls enter our newborns then they will only produce bad people. The battle of good and Evil never Ends,it's fuckin everywhere!!!!!! Keep it positive,the positive souls must take back the earth,if the negative souls win there is no hell,just a big KABOOOM!!!! edit:with theory one souls die at the end of there cycle,only make sense right....To think there is an actually heaven is not following the rules of the universe.....Cause everything dies,even God For the reincarnation theory I could easily follow Newtons law of energy"energy never dies out, it is simply tranfered,never destroyed"
