These guys honestly sincerely believe in evolution. It surprises me people could believe in such pseudoscience.
For much of its history, life on Earth existed as only single-celled organisms. Certain proteins critical for multicellular life, and presumed to have been equally critical for its evolution from single-celled ancestors, require heavy-metal elements, especially copper, zinc, and molybdenum, says John Parnell, a geoscientist at the University of Aberdeen in the United Kingdom. Previous studies suggest that multicellular life evolved sometime between 1.6 billion and 1.2 billion years ago. Researchers thought that before that innovation, these vital metals were locked away from environments where life thrived—either sequestered in the oxygen-poor depths of the ocean or held in ancient ore deposits in Earth's crust, waiting to be eroded.You Owe Your Life To Rock https://www.science.org/content/article/you-owe-your-life-rock
