The Spark of Life, depicted by the Italian master Michelangelo (1475-1564) in his famous fresco of God giving life to Adam in the Sistine Chapel of the Vatican, is a gift from God.
That gift includes the carbon dioxide (CO2) in our atmosphere and the natural process of converting it to living matter, plants and all other life on earth, a process termed "photosynthesis." Photosynthesis is what converts atmospheric CO2 to carbonaceous materials, the principal components of all plants. In turn, with plants being the basic food for all higher life forms on earth, the latter also contain that element.
