Crashing 5x7

I'm not saying the Roswell crash Did or Didn't happen, I'm just saying.. people road horses and wrote letters for thousands of years and grew their own crops and such, That was just Life for thousands of years, and now we got iPads, flat screens and electric cars and there's so much technology that happened in a Very short period of time. I'm only 30 and I'm older than Google, saw the rise and fall of DVD's and now cars don't even come with CD players! How did we advance So much in such a short period of time? Because the way Life is now is Very new and different than what it was just 50 years ago compared to Thousands of years ago.. Did alien technology play any part? I have no idea, all I know is I'm gonna order a pizza and have a drone deliver it to my house.
