In existographies, Euripides (c.480-406BC) (IQ:180|#175) (Cattell 1000:99) [RGM:81|1,500+] (FA:10) (ACR:7) (CR:19) was a Greek philosopher and tragedian playwright noted for introducing the term "bios", the etymological root of the modern "bio-" prefix, for his general "question everything" philosophy, for his view that god was was an invention of a wise man, and for his views on the natural admixture of good and evil.
Bios | Life
The prefix bio-, supposedly, meaning “life” in Greek, according to Georg Misch (1950), originated in one of the works of Euripides. [1]
Euripides scholars E.H. Blakeney (1904) gives the following footnoted discussion on Euripides’ bio- usage: [2]

Here we see the etymology of "bio" intertwined with theology (i.e. meaning "union with god") and afterlife ideas (e.g. meaning "life after death"), among other issues.
The c.495BC fragment 48 (Ѻ) of Heraclitus, however, also uses the term “βίος” in the sense of life.
