> a building in Vegas with some kinds of materials that have strange properties and we don't know where they're from or who made them or how

A lot stranger things have been found hidden in Vegas buildings than alien artifacts. Just a few weeks ago it started raining cheerleader uniforms in downtown Las Vegas because a demolition crew pulling down a hotel hit a sealed-off room filled with thousands of them.

It sounds like you're joking, but you aren't!

It'd kind of beautiful, actually.

It makes me wonder what it will look like when they tear down the building storing old Star Trek: The Experience junk. The UFO conspiracy theorists are going to have a great time with those photo.

You know, I saw something like this in Boston just yesterday. They are tearing down a condemned parking garage near my office; I saw a room they had started demolishing that was packed chock-full with what looks like winter clothes. Like, they had been stuffed in it as insulation or something. Some had fallen out onto the rubble below. Very strange.

If they survive any significant decline of civilization, then the next civilization's archaeologists may suspect "alien astronauts."

I think a warehouse of alien artifacts is stranger than cheerleader uniforms.
