Just because we can't decipher some ancient languages doesn't mean they don't tell us plenty. You may know the famous Picasso saying, "Good artists copy, great artists steal." That's the history of human development in a nutshell. I like my current mouse trap just fine, but if I see one that does a better job than mine, I want to know why and how and if I can figure it out, I'll upgrade my next mouse trap model. It's why we have corporate and military security and espionage.
I think there is solid, verifiable evidence that we have reverse engineered alien vehicles. I'm not going to tell you I think it adds up to case closed proof, but the evidence is strong enough to merit a closer look.
FFS we're reverse engineering spiderweb to eventually make 'stronger than steel' cables. And then there's what you can call 'inspiration': 100 years ago or so... looking at birds, a couple of brothers decided they'd try building an airplane.....
Not to mention... that its the first thing warring nations tried to do throughout history... copy the other guy's tech.
