When Did Stars Create the Chemical Basis of Life?

This paper gives a review of the latest observational data on early stellar nucleosynthesis in the Universe compiled on the basis of an invited report at the “Astronomical Problems of the Origin and Development of Life. The Young Sun and the Earth” meeting-discussion dedicated to the memory of Academician M.Ya. Marov, March 19, 2024.
