I guess... you’d be a science fiction writer..? You’d have all these fantastic sounding ideas- but couldn’t explain exactly HOW they worked- you’d just know that airplanes can fly and we can send information across huge distances and have bombs that can level entire cities. And maybe people would just say: “wow. That person has the best stories. So much imagination- and the way it all fits together so well and the way they tell it makes it seem so real!” And then perhaps- after you left the past or died in those ancient times almost before recorded history- your facts that people took as fiction would be seen as fact again- give births to legends like the sunken city of Atlantas and all the amazing things they had.
Then those stories will be found and passed down and treated as fiction again. But they will inspire writers like Jules Verne to create tales of fiction that will inspire inventors to create the things we have today. Then someone will build a time machine- you’ll go back in time and tell your stories....
But... in the year 3500- perhaps others will do what you did. Travel back to THEIR ancient past- the 1960’s, 1980’s, 90’s, 2000’s. And perhaps they too will know all kinds of cool things but not really how they work. And they will tell us all about them- and maybe, just maybe- your favorite fiction writer or world builder isn’t an intricate genius- maybe they are a time or dimensional traveler who just really doesn’t understand the technology and workings of where they are from- but can tel you all about the politics and poo culture and everyday gadgets they have seen and used. I dunnoh. Maybe.
I've put a bit of thought and done a bit of research on this topic. Short answer is you'd probably just be killed. Most cultures in the past didn't put much value on life and it's extremely doubtful you'd be able to even speak to people for quite some time until you learned the language. Generally speaking you'd only be able to travel 150 to maybe 200 years into the past and still be able to communicate with anyone at a fluent level. Being able to speak at a fluent level, unless you were stupidly lucky, is kinda a prerequisite to trying to explain technology. Even assuming you knew how, had the technical skills needed, and materials given to you most of the tech we use today just plain requires too much other tech to even create. Generating electricity is actually one of the easiest things to do but being able to use it? That's tough. And without tangible results hardly anyone is going to care or even give you the time of day.
