To add more on “what we don’t see”: if some UAPs are aliens, why have they been on earth for decades, but they haven’t done anything yet other than fly around? Why have they never landed (or, if they’ve landed, why did they only land at secret military bases)? My prior is that if intelligent aliens visited earth, they would do one of two things:
They arrive in force, and their presence quickly becomes undeniable.
Their scouts arrive and fly around for only a short time.
It seems a lot less likely that they’d arrive, fly around for decades, get spotted several times, but only ever in the distance.
