Hello everyone! I'm writing my first fantasy story and wanted to get some advice. Ever since I started, I've been nagged by the problems associated with writing a story that has identical technologies as earth, but on a planet that is not at all earth. My frustration is also compounded, I think, by the timeline of my story, which takes place in three distinct periods: a distant past (say, the equivalent to our 10,000BC), a present (equivalent to our 1930s technology) and a distant future (thousands of our earth years ahead). I've gone so far as to come up with an entirely different earth-like planet, and doing so took a ton of research (coming up with how many days in a year, celestial, orbiting bodies, geological systems, etc) and it gave me pause; am I thinking about this way too hard? For some reason, these things never bother me when I read fiction, but keep poking me when I write it. Take language, as an example. There are all sorts of languages in my story, but the main language is English. Of course it's not called "English" in my story, but since it is not a Latin-based system, do I simply avoid using words that have strong etymologically earthen roots? Take the word "galvanize", for instance. The word comes from Luigi Galvani, a physician and physicist who studied electrical stimulation in animal tissue. "Galvanize" is a great word, though! How then, do I reconcile a character of mine saying that in my story? Do I just assume/trust the reader understands they are not speaking "English" per se, and it's more about the meaning than the words themselves? Technology, as mentioned before, is another example: there are cars, planes, revolvers...all things here on earth. And, not to mention, they're driven, flown and shot by humans with two arms, two hands, five fingers - all the same here. Is this something I really need to justify, and if so, come up with a backstory how these things developed on a planet that is not quite like earth, but very close to the one I live on? Again, I'm sure I'm thinking waay to hard about this, but I'd love to see if any of you out there have felt this way and what you did to come to terms with it. Thank you all ahead of time for giving this some thought!
