“But the fact Is there is 100% evidence for life here and so far zero for life anywhere else.” Such an assertion belies your narrow narrow narrow class for proof. There are memos between top military folks in the fifties which contradict your assertion.

I don’t think this topic includes it either.
No scientist who argues for other inhabitable worlds uses UFO stories as evidence.
That’s really a different topic.
