Not sure if I should post this question here or in the Materials & Chemical Engineering forum but I will give it a try.
If I were to take several modern items, let's say an iPhone, a set of chrome vanadium steel wrenches and a stainless steel/titanium Smith & Wesson revolver and bury them at a variety of places on Earth what would be found in 10,000, 50,000 or 100,000 years? Anything resembling items made by a technologically advanced culture?
The reason I am asking is this: If the Earth was visited by extraterrestrials in the remote past wouldn't there be something left more convincing than artistic renderings of bizarre creatures and "flying saucers"?
