[Our moon] “…turned out to be something I didn’t really realize what it really was!…”

In Netflix’s “Top Secret UFO Projects Declassified: Hacked and Leaked” (ep. 4), there’s a Private corporate Sandia Labs “Library”, inside Kirkland AFB (1990-1998) which is discussed. USAF Surgical Asst. Emery Smith who allegedly worked there for [I think] 27 years says there was a highly-detailed 3D interactive Earth moon model and that our actual moon, “…turned out to be something I didn’t really realize what it really was!…”. The clip ends with Smith stating that with a smirk on his face and then the episode turns to a completely different chapter of the episode. WTF! Does anyone know what Smith was eluding to?! And why it was 100% skipped over in the doc?!
