It is illogical to think we, as Souls, are limited to one human life.
The human experience cannot be captured in just one short life span, in just one body.
Thus reincarnation, for the eternal Soul, through some periods within eternity, appears to be the most rational explanation.
It is not illogical to also speculate that Souls may also reincarnate through many levels of species.
Scientists have estimated there are 300 million species of life forms on this planet.
And, that there could be 50 sextillion planets in this universe
that could support life.
And if other universes exist?
