Adam — Created Alone

Jewish tradition places enormous theological weight on a single, deliberate detail of the creation narrative: humanity did not begin with multiple people, or with a Jewish ancestor and a separate non-Jewish ancestor, but with one single human being, Adam — who was, notably, not Jewish, since the Jewish people did not yet exist. Every human being who has ever lived, of every nation, descends from that one shared ancestor.

Why the Sages Say Humanity Began With One Person

The Mishna treats this as far more than a narrative detail — it draws out its ethical implications explicitly, in a passage traditionally recited in Jewish courts before witnesses testify in capital cases:

Therefore was man created single in the world — to teach that whoever destroys a single soul, it is as if he destroyed an entire world. And whoever saves a single soul, it is as if he saved an entire world. (Mishna, Sanhedrin 4:12; Kaufmann edition)

The same passage goes on to draw a second, equally deliberate conclusion: because every person on earth is descended from the same single ancestor, no one can claim superior lineage over anyone else — "one may not say to another, 'My father is greater than your father.'" A single common ancestor for all humanity was understood by the sages as a built-in refutation of any claim that one nation or lineage is inherently superior to another.

The Foundation for Universal Human Dignity

Because the starting point of humanity is one person, created with the image of God, before any nation, religion, or ethnicity existed, Jewish tradition grounds the dignity of every human being — Jewish or not — in something prior to and independent of religious or national identity. This is the theological basis for teachings such as the repeated biblical command to love the stranger and the broader Jewish ethic of universal human worth: every person, of every background, carries the same inherited dignity as the one shared ancestor from whom all humanity descends.
