Lord Kelvin and Space Seeds: The beginnings of life on Earth (and perhaps elsewhere) is one of science’s most enduring mysteries.

The article explores the historical development of theories regarding the origins of life on Earth and the possibility of extraterrestrial life, focusing on the contributions of notable figures such as Immanuel Kant and Lord Kelvin. It discusses the shift from the ancient belief in spontaneous generation to the idea of panspermia, proposed by Kelvin, which suggests that life could be seeded on Earth through meteorites carrying microorganisms. The article highlights the evolving understanding of the universe, emphasizing that both Earth and other celestial bodies were once lifeless and that life may have originated from external sources rather than spontaneously from inanimate matter. Ultimately, it raises questions about the commonality of life in the universe and the ongoing mystery of how life began. [Extracted from the article]
