There is no inherent meaning of life, life occurred through natural processes and conditions.
Though this shouldn't devalue our lives, but rather empower them, rejoice in the fact that at this moment, you exist, because million years ago, stars died (as they all do eventually) spilling their chemically enriched contents out in cosmos, forming planets, including ours. Those very same elements make up your body. You are star stuff, we are all star stuff, and for a brief moment, amidts the chaos, through billions of years, those elements coalesced to form you. Our time in this planet is limited, love those who are around you, cherish it, savour it.
