We have to realize that were we to go to another planet, we would describe that planet with our own terminology and according to our own experience. Whether or not our observations were "ancient-sounding" or "post-modern" would have to be interpreted by those reading our words. If you read prophesies in the Book of Isaiah in the Bible, he describes horseless chariots as future modes of transportation. Is he talking about our automobiles? If so, he described them in his own way of understanding for the time period he lived in. I think we would do the same if we were to see into the future or to visit another planet totally unlike our own.
