Is death the end of the road or the beginning of a new life?

I want to believe that the soul's life is infinite... But... "Many people dream of immortality, but don't know what to do on a rainy weekend." :) I partly adhere to Tsiolkovsky's theory - that consciousness is a molecule, and as a result of the cycle of matter, each atom repeatedly ends up in brain cells, meaning we live infinitely, and our consciousness is reborn, but we no longer remember our past life... This is too materialistic, quite convincing (I am Orthodox only in baptism, but otherwise I am almost an atheist and I treat all religions with interest; besides, I need convincing and realistic evidence for everything, so I am not a believer by definition), but... still, I prefer the classic version of reincarnation, when the immortal Soul takes on a new form each time. And... I don't know why, but it seems to me that everything created by humans exists somewhere in another world. Who knows - maybe famous writers, directors, and artists created works about themselves and their friends and acquaintances in a past life, without even realizing it? Anything is possible...

P.S. In short, as always, I've philosophized so much that I don't understand anything myself :)
