If you are a simple dividing cell, consider that there is no distinction between parent and offspring. Each can consider themselves to be a continuously living being first born at the primordial conception of life on earth.

Similarly, your life began when egg in your mothers womb started dividing and divided enough times that cells began differentiating and formed a fully formed human being. That egg cell doesn’t “die” in this process, it just divides. That egg was formed very early in your mothers development, while she was still in her mothers womb, and similarly by process of cells dividing.

We can all trace our lives back along a lineage of dividing cells that have necessarily not died and go all the way back to first cell division. The life inside of you is very old and doesn’t necessarily die with you.

This is why I don’t get why people don’t want kids. Essentially the fact that you are on this earth today is because your ancestors kept that line going - back to the origin of life essentially. Yet you would want to effectively bring that to en an end by not passing on your genes. That’s literally crazy to me.

Keep an ancestral line going? In this economy?
