claimThe discovery of Earth-like DNA/RNA/carbon-based life on Mars would not indicate that life is pervasive in the galaxy, but would instead suggest that life on Earth and Mars shared a common and singular origin.
perspectiveThere is no evidence to suggest that RNA/DNA cells spontaneously originate in Earth's extreme environments, as biological adaptation is distinct from the origination of life.
