Yes! You see! only after Roswell did the vacumm cleaner, x-rays/ other waves experiments, and the B-2! Let's not forget the B-2 bomber! A tiny and thin airplane that holds huge bombs! A human didn't come up with that by itself! I REST MY CASE!
Okay lets look at things logically here.
The Vacuum cleaner. This is the first time I have ever heard of the good old Hoover being a piece of alien technology, and is laughable. The vacuum's origin goes back well over a hundred years where a large steam based engine would traverse the streets and offer a door to door vacuum service.
X-Rays. Well the first medical X-Ray was used in 1895, a little before Roswell's time.
The B-2 Bomber. Rocketry and design is responsible for heavy pay-loads, and these are a natural progression from the more outdated form of air propulsion. Stealth would be a more reasonable assumption of alien technology, but even that is a natural progression from the original developement of Radar, and it is this that gives the B-2 its unique shape. If you were to ever stand next to a B-2 Bomber I am not sure you would describe it as tiny and thin.
No you are right, a human didn't come up with that by itself, but a long and steady procession of HUMAN'S did over the course of time.
There is one trend with all of the examples here and many that arent. The initial principles do not change. The B-2 flies and drops huge bombs, the flying fortress flew and dropped huge bombs, whats the difference? One utilises rocketry principles, the other does not. A gun, now modern small arms are lightyears better than say a gun 200 years ago, but the principle remains the same, it uses a controlled explosion to propell a missile down a length of tubing at a large speed. What's different? Well, essentially it is the ammunition used and the perfection of the original principles, of course there are springs added and even computers in some instances, but the principles are the same.
I think the major point here is, just because a lot of people are unable to simply comprehend a fraction of the science behind things does not mean that the whole of the human race is as stupid as they are. Give ourselves some credit, aliens did not create the world we live in, we did. Sometimes I think that the belief in alien visitors is a modern surragate for god, and instead of god giving us such wonderful things, it is aliens.
I REST MY CASE
