I believe that there are many methods between heaven and earth than science can explain. There are ghosts, spirits around us. They are nothing more than energy without any physical traits. Thats why they cannot interfere with our conscious world. They can only watch. From the ghost, spirit state they eventually move on. Materialising into a baby that's getting born. Sounds weird? Well. I believe in an endless cycle l, call it reincarnation. "We" form from energy and return to energy, just to form a new life again.
