Did aliens give us our tech?

Random thought of the day. Since the dawn of time, approx. 5000 years ago, we began to actually record history. So we really only know our culture from 3000 BC to the present. But humans have existed prior to that, we just didn't record anything down so we only have limited knowledge. However, our technology is known since those artifacts have been and are still being found. And our technology didn't really advance much over thousands and thousands of years. Horse drawn carriages, torches, metallurgy and blacksmithing and what nots have been the tools we used for milleniums. Like, literally, thousands of years. Then, all of a sudden, BOOM! We have this....this crazy technologically advanced world. And when did it all start? Roughly within the past 150 years. Maybe even less than that. We made cars, discovered how to harness and control electricity and now we can talk through radio waves, shoot humans out of this protective sphere into the deep dark void, and literally store our lives on electronic devices that relies on a mathematical concept called "imaginary numbers." OOOOOOOOH, sexy!

So, any theories on how for thousands of years, our technology was pretty much, eh, and now we can do just about anything we want, anytime we want to do it? ALIENS! That's right motherfuckers. We have alien technology. There's no other fucking explanation, right? I mean, come on, it's pretty fucking obvious, some how, we got a hold of some technology that wasn't natural on Earth or for humans and that took us to this imaginary world that relies on imaginary numbers.

Makes sense.
