I would compare life to painting a room in a burning building. When you have finished painting the room, the fire will consume everything you have done, there will be no sign that the room was ever painted. When our bodies die, the memory of what we have done is gone and the activities of our lives no longer exist, eventually we will be forgotten in this world and everything we do will be for nothing. Atrophy will waste everything away into nothing and one day there will be nothing in this world and there will be no evidence that we lived, it would almost be like nothing ever happened. There will be no Earth, no stars, no material, just nothing.
I often watch NDE(near death experience) videos on YouTube because I want some evidence that our life persists after our bodies have died. I want proof that we have a higher cause and that there is more to our existence.
