For all we know our meaning of life could quite possibly be totally wrong. Humans try so desperately attach reason to why they exist or live, when there could be no reason. We just came to be and our time will pass, like dinosaurs and other creatures that roamed the earth before us. Humans will go extinct long before the planet dies.
unless we end up killing the planet i believe the meaning of life is to live ab=nd carry on the species
The purpose of life is to serve God our creator so that we can prove to him that we are worthy. Of course none of us are worthy because of sin, but if we don't accept him we will burn in hell.
