The Kamitakamori tools? Piltdown fossils? The pattern roughly seems to be "if you have physical artifacts that support a theory / fit a pattern they will be accepted (even if bogus) but if you have a theory that explains facts (e.g. drilled holes) but no physical artifacts (in this case drills) it will be rejected".

(Just saw the snark about ancient aliens; no idea where that came from. If you're going to try to imply that that's my position you'll need to produce some artifacts to back it up.)
