Fear of death ultimately reduces to thwarted biological survival instinct.

Evidence

Unlike bats and worms, however, we humans know that no matter what we do, sooner or later we will lose the battle against death. This is a profoundly unnerving thought. We may think we are afraid to die because our bodies will rot, stink, and turn to dust, because we will leave our loved ones behind, because we’ve left important things unaccomplished, or because we have the sneaking suspicion that no loving God awaits us, ready to enfold us in his arms. But underlying all these concerns is that fundamental biological imperative. As Juliane Koepcke and other survivors have discovered, we will do just about anything to stay alive. Yet we live with the knowledge that this desire will inevitably be thwarted. — Sheldon Solomon, Jeff Greenberg, Tom Pyszczynski, The Worm at the Core, 42
