According to Trench in this book The Sky People, Adam and Eve, Noah any many of the other characters from the Bible originally lived on Mars. Trench believed that Adam and Eve were experiment creations of extraterrestrials. His claim was that the Biblical description of the Garden of Eden was inconsistent with what was on Earth and as Mars contained canals, that the Garden of Eden must have been located on Mars. He further claimed that the north polar ice cap melted on Mars, and this caused the descendants of Adam and Eve to move to Earth.
