If you ask me why are human exists? I simply say because of fear of death… Through many million years of evolutionary processes. You had also heard it from many spiritual people that humans are here because of fear of death. So let’s suppose you hve not be given food and water for 3-4 days now what happened to your body? Your mind will harshly request you to drink water and eat food otherwise you will died. And that forces your body to move any place you want but quickly eat food and drink water.
Let’s take another example. You are left in ladakh mountain ranges without warm clothes in very very cold climate. Then your mind sent urgent signals to leave the place or wear warm clothes or move to a warm place otherwise you will died. So it is called fear of death. All living beings are selfish on the point of their life. And it is the most important aspect of our existence. Or else we will die and everything khatam… 😂
