When we were a young child full of wonder at the world, so new, so innocent, we believed what ever mommy and daddy told us, if they said there was a tooth fairy why we believed it until we got older(hopefully) especially when we get our permanent teeth.
Santa was probably discarded around the same time as the Tooth Fairy give or take a few years depending on gullibility or lack of it.
Well lets face it we probably figured out the Easter Bunny first for the simple reason you only got some eggs,, which you can have any day of the week and you get to eat a lot of chocolate bunnies ears off not very pious mind you, nor do you fear the bunny might seek revenge for the impious act in some way like God might do remembering: the Ark and Ussa or Wassa or something. That definately should be considered as a contributing factor as to why and what order they get debuncked tooth fairy danta the benifit factor need to be brought in.
God too has to go in time, eventually, just like not all at once and for everybody. Religion to control the mind is on a head on course with human species vastly excellerated enlightenment. Religion has to change in order to prolong its years with the species and have some power to control thought but soon as the human species grows in understanding its gotta happen God will be discarded just like the Easter Bunny,, ya know what I mean interesting to talk about, but just once and a while excluding history buffs of coarse.
