Summarize this article for a 10 year old
Günter Wächtershäuser (born 1938 in Gießen) is a German chemist turned patent lawyer who is widely known for his work on the origin of life, and in particular his iron-sulfur world theory, a theory that life on Earth has hydrothermal origins. The hypothesis proposes that early life may have formed on the surface of iron sulfide minerals, hence the name.[1][2][3][4][5] It was developed by retrodiction from extant biochemistry in conjunction with chemical experiments. The theory is consistent with the hypothesis that life originated near seafloor hydrothermal vents. He was encouraged and supported by science philosopher Karl R. Popper to publish his ideas.
