Define "perfect".
The, arguably, ancient position we see among the fathers is something along the lines that Adam and Eve were created "imperfect", that is with room to grow and mature. St. Irenaeus in a sense saw the Fall as a kind of adolescent rebellion. Jesus Christ is the mature man into which Adam was to mature to become--that is, in Jesus we see what being human is supposed to be--the Fall did not stop God's purpose, and maturity is found in Christ; and we shall reach the full measure in the resurrection as we become like Him, being glorified on the last day, consider Irenaeus' statement, "He became what we are that we might become what He is."
Though usually "perfect" is meant to indicate a moral perfection, that is without a moral defect; to that end the story says Adam and Eve did not know evil until they fell, they were therefore entirely innocent. So we could say they were "perfect" in that sense.
All creation was perfect in the sense that all creation was created "exceedingly good"; but not in the sense that there was no room for growth, maturity, or potential.
