Why Are Adam and Eve Not Holy?

The Catholic Church recognizes around ten thousand named saints. Adam and Eve, the figures named on the very first page of the Bible, are not on the list. Almost every culture in human history names a First Couple. Modern molecular biology named one too, in 1987, and even materialist geneticists reached for 'Adam' and 'Eve.' This is the long answer to why the West specifically demoted them, why no major culture has ever practiced active worship of the literal First Couple, and why Mitochondrial Eve and Y-Chromosomal Adam are the first First Couple in human history who are not characters in a story.
