MATTER & ENERGY ARE MATERIAL MANIFESTATIONS OF THE ETERNAL TRUTH

Atma/soul is eternal; matter-energy may become it's variable identities for various roles in the universe. When atma wears sun, it becomes Sun-god and controls behaviour/properties of our Sun. Likewise, if Atma wears human, fish, tree, microbe, etc matter-energy wherewithal - it becomes it's body Identity till that body remains a workable/usable machine/system. When a workable system becomes unusable, it is discarded as 'dead' and its Atma with life-long gist of experiences enters the next usable form (rebirth with infinite quantized possibilities within Godhood unlimited), implies Srimad Bhagavad Gita. So, death is just like discard off nonperforming protoplasmic or other matter-energy clothes and wearing new ones, explained Sri Krishna about 5500 years ago.
