In my SciFi book, 400 years from now, humanity has expanded throughout the solar system and managed to survive the death Earth. In their history, Earth fell during the third world war in 2093 CE and the five existing colonies in the solar system (Luna, Mars, Venus, Callisto, and Titan) were all that was left of humanity. Fast forward 336 years and humanity refers to WWIII as the "Earthfall", the next 49 years as the "Schism" until the five colonies and rogue fleets were united under a single unified government, which is then referred to as the "Formation".
Now with that general background in mind, what would the people of that future refer to our current time period as? (e.g. Middle ages, Renaissance, Industrial Revolution,...etc)
I don't intend for this to be an opinion based question as I am looking for terms that actually might already be used if there are any. Please site a source if it isn't a term that should be easily recognized and I have somehow completely forgotten it. I am discounting terms like "The Digital Age" and "The Modern Age" as everything in the future is likely to continue to be digital, and "modern" means now, which obviously won't be the same for people in the future. Also, if this has already been answered or is too opinion oriented please let me know in the comments.
