Which Pope(s) claimed that the Creation Story (Adam and Eve) is a myth or allegory?

And I need proof! I believe both Pope John Paul II and Benedict have acknowledged this, but I need to be provided with evidence (and not just an article claiming they said it, I need quotes and possibly a primary source). 10 points are up for grabs, please help.

The following is a speech Benedict XVI made to the Pontifical Academy of Sciences. In it he states Evolution is what the Church believes, it explains what their view on Genesis is. Here is him quoting John Paul II

“scientific truth, which is itself a participation in divine Truth, can help philosophy and theology to understand ever more fully the human person and God’s Revelation about man, a Revelation that is completed and perfected in Jesus Christ. For this important mutual enrichment in the search for the truth and the benefit of mankind, I am, with the whole Church, profoundly grateful”.
