Why is life so short

Idc ab punctuation and never will I guess we really have no purpose in life which I just realized and I’ve been trying to think else wise but I can’t no more and I just feel dead about it to be honest I’m already 20 and I probably have like 65 years left and I know it’s long but it’s really not just look at how old the universe is like I feel like if something were to put humans on earth and give them no afterlife at least make the time here longer cause its kinda bs and I’m starting to have trouble relating with people they don’t understand just work till they die and to me I just want to find the meaning of life I hate living in question

Idk no more I’ve tried all I can do to try and believe but none works even just understanding life makes no sense and how everything works and just what is the purpose if we just die on this earth that also has no purpose yet are lives are so crazy strangely fuckin detailed even if humans made it themselves whatever we came from maybe something always had it or maybe something put it there who knows
