The reason for the existence of all sentient beings is to enhance awareness. The old seers, risking untold dangers, actually saw the Indescribable Force which is the source of all sentient beings. They called that indescribable force the Eagle, because in the few glimpses that they could sustain, they saw it as something that resembled a black-and-white eagle of infinite size. They saw that it is the Indescribable Force that bestows awareness and creates sentient beings so that they will live and enrich the awareness it gives them with life. They also saw that it is the Indescribable Force, that devours that same enriched awareness after making sentient beings relinquish it at the moment of death. For the old seers to say that the reason for existence is to enhance awareness is not a matter of faith or deduction. They saw it.
