Hold a pebble in your hand for a moment. Then shift your palm to your chest and feel your heart beating steadily beneath. At first glance, the two could not be more different—one is silent, cold, and unmoving, while the other is warm, alive, and full of thought. Yet at the quantum level, they are surprisingly similar. Both the pebble and your body are made of the same elementary particles, governed by the same physical laws.

So, what creates the gap between living and non-living matter? What gives one cluster of atoms the ability to breathe, love, and dream, while another lies inert on the ground?

For me, the answer lies in something more elusive—the soul.
