Technically, Jesus  created the institutional religion that is the Catholic church when he said "you are Peter, and upon this rock I will build my church."  Who are we to say that we know better than Jesus?  Incidentally, which parts of the Catholic faith do you consider to be "fictitious presumptions"?  Also the things you are stating about "belonging in and to nature" seem to have a very pagan slant, unless I am misinterpreting them.
