One cannot pick and choose. If one believes in the Genesis account of creation, one must believe in the True Presence in the Eucharist. That was Martin Luther’s theme point too when combatting with Zwingli
No problem believing in a literal Genesis but I suspect that our definitions of the True Presence in the Eucharist would clash, not because the text is clear but because RC's see the True Presence actually in the Eucharist (physical body and blood) while Protestants see the True Presence in the Eucharist (Christ's presence with us during the Eucharist).
I can't say if the Catholic position is true or false, as I've never received the Eucharist as a Catholic, but I can say that I've seen the evidence of Christ's presence during the footwashing and communion services that I've been involved with, including on at least one occasion a true to Scripture occurrence of speaking in tongues, complete with independent translation by a 3rd party.
I know which one that I believe to be correct, but since I can't be completely positive on the matter I refer to Mark 9.
Mar 9:38-40 KJV - [38] And John answered him, saying, Master, we saw one casting out devils in thy name, and he followeth not us: and we forbad him, because he followeth not us. [39] But Jesus said, Forbid him not: for there is no man which shall do a miracle in my name, that can lightly speak evil of me. [40] For he that is not against us is on our part.
