What if reincarnation was just a religious misinterpretation of the concept that all your matter will be recycled infinitely into the environment as compost, then grass, trees, salmon, bears, beetles, mushrooms and bacteria etc, all at the same time.

Under the principle that you are the universe experiencing itself subjectively, recycling yourself now or later makes little difference on your endless journey other than being a wasted opportunity for experienceing it all. A human has an amazing opportunity to experience thought, music, wine, chocolate, love and all the other things in the way a mushroom likely doesn’t.
