It will be an exercise in futility to discuss these artifacts to which I alluded since you have a large blindspot in your reasoning axioms: "AFAIK, "Intelligent being", is basically limited to the genus, Homo."

I am absolutely sure that Angels are intelligent beings. As beings I would apply the axioms as often offered by Alamo_Girl on these threads: 'without space things do not exist; without time events do not occur.'

"As beings I would apply the axioms as often offered by Alamo_Girl on these threads: 'without space things do not exist; without time events do not occur.' "

I'm afraid I don't quite follow that logic, -- BUT...

Please remove my constraint restricting the definition of "intelligent being" to the genus , homo.

Now, the "working" definition of "artifact" is still,

"an object with evidence of being formed, modified or used by an intelligent being".

Again -- If you have actual data re artifacts from planets / satellites other than Earth, please share them...
