Although, perhaps we do need to begin at the beginning. What else should we do with our time on Earth except rediscover the truths of life in each and every age.
Perhaps like the seasons, humanity follows a perpetual cycle of growth, abundance, decay, and dormancy. To maintain itself, an eternal system would likely include a means of decomposition and subsequent development.
Maybe each of us grows as an annual flower. Maturing within a lifespan until propagated by seed into the next. A seed that’s been shaped by the flower it dropped from, imprinted with an essence of what came before.
