Since both of them are true, there cannot be any conflict between them. Truth cannot contradict truth. Jesus Christ clearly demonstrated that He was God, by constantly doing things only God could do. He, God, founded one Church, said it was to remain one, and promised that one Church the fullness of God's truth until the end of time. Since its teaching is guaranteed true by God Himself, that teaching never conflicts with natural truths revealed by science. Truth cannot conflict with truth.
