This is what the Catechism of the Catholic Church has to say about this:
“The account of the fall in Genesis 3 uses figurative language, but affirms a primeval even, a deed that took place at the beginning of the history of man. Revelation gives us the certainty of faith that the whole human history is marked by the original fault freely committed by our first parents (#390).”
