Here's why i think life on earth matters the most (personal opinion)

So I've been thinking a lot, about the afterlife and the way it works.. i was like okay maybe after an amount of time we'll start to forget a few things, and when that happens, after a very long amount of time we might get reshaped to a completely different person and forget who we were before. Which sounded absurd to me, as if whatever we do here is pointless, the lessons we learn, the people we meet,

But, i think the memory lives we live on earth will be stuck with us forever, and be the one who shapes us into what we truly are and to keep navigating through the afterlife without losing ourselves or who we were. That's why it's important what we do here and the experiences we have, because it will be the only memory that'll never fade. And that'll put us in a place we belong to later on

Also, one more thing I've come to realize, that the reason we exist, is because we simply cannot ( not exist ) we came from one source, that keeps expanding like a tree with endless roots, if one wishes to fade or end his consciousness or individuality, they'll simply return to the source, and either their soul gets "recycled" or they'd stay with the source forever (god). Either way, they'd still have a form of consciousness.

These all a bunch of stuff i concluded after I've spent like Seven months searching around for answers, and these are the most reasonable answers I've got.. I'd love to hear your opinions on this
