Scientists have said that the earth was formed about four and a half billion years ago. If this figure is correct then we must assume that the human spirit has been here for a very long time. The human spirit germ incarnated on earth midway in the cycle in the development of the earth. The human spirit has therefore been here longer than most of us suspect. This indeed would correlate with the long periods it would have taken for us to evolve into what we are today. The gradual slow development, the slow process of raising the animal body to the state it is today, the development of language through the descent of the larynx, the gradual evolution of culture are all processes which must have taken an enormous amount of time.
