The author seems to be referring to the Declaration of Independence "all men are CREATED equal" and "endowed by their CREATOR" with inalienable rights. He claims this concept was forged by science and ignores the Christian roots of the concept of equality.
Romans 10:12 - For there is no difference between the Jew and the Greek: for the same Lord over all is rich unto all that call upon him.
Galatians 3:28 - There is neither Jew nor Greek, there is neither bond nor free, there is neither male nor female: for ye are all one in Christ Jesus.
Colossians 3:11 - Where there is neither Greek nor Jew, circumcision nor uncircumcision, Barbarian, Scythian, bond nor free: but Christ is all, and in all.
It can be argued that scientists developed racism. "Notes from Virginia" show how much Jefferson was influenced by the anthropology of his day, and the longer he lived the further he moved from the Lockean view, which was essentially Christian, of the natural equality of man to the 19th century theory of essential differences between races. That is one reason why he supported slavery. Science taught him not to regard his black slave as his natural equal.
I am neither Greek nor Jewish so I guess all that does not apply to me.
