Similarity between the Exotic metals and Contactee accounts of craft?

Going through different testimonies of encounters, starting with military accounts and then civilians, I began noticing clear similarities in their descriptions.
Mario Woods encountered what appears to be Greys and describes the same features as Alec Newald, an alleged contactee who claims to have spent 10 days in “Haven,” a Grey dwelling.
Then there’s Simon Parkes, a Mantid contactee, describing the same smooth, spherical interior of craft with energy-like panels throughout, matching what Mario Woods reported.
Bob Lazar describes the “sports model” craft as almost seeming 3D printed. Simon Parkes says the same thing, that these crafts are “grown,” which is also supported by Alec Newald.
This is only a small part of a larger series I’m working on, but I wanted to share these details to bridge the experiencer accounts with more widely known military encounters that often hit the bigger SoMe channels.
There’s a lot more, things like “The White Room” and some kind of school that Whitley Strieber and other civilian contactees also reference.
Dive in and look at the data. More is coming.
