So if we assume as a starting point that one of these physical objects is indeed sent to us from an alien world. That means that some or all of these must be true:

It’s a technological society
To manufacture technology you must extract resources from your planet
You need to produce energy
You need a solid surface to construct on
You need an atmosphere that is not hazardous enough to kill you
You can access the stratosphere and beyond
You can overcome the local effects of gravity

This implies to my simple brain that any entity sending such an object is likely to:

Reside on a rocky world that’s not too big
In the goldilocks zone
Is a surface dweller or at least has free access to a surface
Is biologically structured so that they can physically manufacture and operate technology

In other words, more likely to be exposed to and the product of similar pressures as us than not

And I’m not in any sense talking about any/all intelligent life - just something that would send a physical object like this subject to the pentagon report

Just to clarify, this was the focus of my earlier comments also

And not saying I’m right. I just find this a really interesting discussion so happy to hear different views
