Where Am I ?

Not only a single Universe is existing ! Modern Science is predicting about Multiverses Our whole solar system holds the same position compared to a single sand particle in Satara Desert : I am totally confused about my identity in this vastness. No idea, when or where or how to enter or exit . Where are these worlds ! Onward - backward! within Space - time boundary or beyond, might be Spiritual realms in fourth dimension above human perception ! My existence in this Earth is beyond my explanation. I am born in this Earth through inevitable Evolution and approaching Death on natural process. I can't assess what's waiting in my 'After-Life ' phase ! I can neither assure about immortality of so-called 'Soul ' nor any knowledge about re -incarnation, Yet I wish to believe in both. Actually, no doubt that this belief to sprout from wishful thinking of Humankind. No human being can't think of his or her complete extinction.
