Sure, there is always a possibility of return, at least on a 2d plane (not 3d), but still mathematics will have to be revoked to favor low probability macrostates. Certainly an ambituous goal!

Nah, you just account time to explain life

There is a hypothesis that life emerged because living things dissipate energy more efficiently[0]. As one possible implication, individual immortality given humanity as we know it might appear counter to that goal. As a more far-fetched implication, evolving humanity in a way that motivates accelerating efficiency of energy capture and dissipation even as individual longevity increases could theoretically unexpectedly inch us closer to immortality.

Or the source of life lies outside the physical plane. Modus tollens to the rescue!
