Martin Buber elaborates and expands on this axiom in a way that includes us all:
“Every person should know and consider the fact that you, in the particular way that you are made, are unique in the world, and no
one like you has ever been. For if someone like you had already been, there would be no reason for you to be in this world.” (Ten Rings: Hasidic Sayings, Martin Buber)
Here's a big picture view from the Sikh scriptures of India, the Adi Granth, Peace Lagoon translation:
"It was for the sake of the God-conscious beings that our True Lord created this earth, and began this play of death and birth".
