What kind of evidence would you prefer?
Ok, let's go ...
Most importantly,
no testimonials (by
no-one, not even the POTUS

), only
physical evidence! We've had enough stories by
now.
For starters, the evidence could be:
- Photographs of artifacts on the surface of the alleged facility, like e.g. vents, access doors, surveillance equipment, intrusion sensors, whatever.
Photos must include a readable display of a hand-held GPS receiver, so that others can independently verify the location of said artifacts. There must
be
some access to the facility, and because the surface is allegedly
no restricted area, one should be able to obtain such photographic
evidence.
- Videos of operations near the alleged base, in a quality which makes it possible to actually discern something. Nighttime video which shows only
blobs of light won't do. Again, a GPS display must be in frame at least once.
(As for the GPS data requirement, it's simply necessary because otherwise you could photograph/film just about anything anywhere.)
More advanced evidence would involve smuggling of material by base personnel. So, photographs and videos from
inside the base would be
appreciated, together with GPS receiver data.
So far, all this evidence could also be faked. Therefore the more complex (and therefore difficult to fake for amateurs) a video is, the more
compelling it is as evidence. Therefore I exclude printed documents, because these are just too easy to fake.. Sorry, but extraordinary claims require
more than "vanilla" evidence.
Finally, the best evidence would of course be physical artifacts, like, say, an alien tool. I think we can assume that the aliens brought some of
their hardware themselves. A metallurgic lab can quickly prove, if some artifact is of terrestrial origin or not. At least, a piece of metal which
could be extraterrestrial takes more means to fake than are available to the general public. I agree that such an alien artifact would only be
very strong evidence of the presence of extraterrestrials on this planet, but not necessarily at Dulce. However, if someone proves that the ETs are
here, I'll grant you the existence of Dulce for free

.
So, that's it. Now, Mr. Lear, please show us any evidence as defined above. But I won't hold my breath ...

P.S.: @Mike_A: Do you want to add anything, which could count as evidence, too?
