The anser to the topic title iz yes. It iz evidence against UFOz being from distant star systemz.
Its not proof.
The science coud be rong and there can be other factorz that negate or circumvent it.
For example, the UFOz coud hav simply spent thouzandz or millionz uv yirz getting here. The alienz are likely to be immortal, so why not?
The nee jerk objection to that iz 'why woud they come here' but who sez they arent just wandering around to all the systemz with planets? The space ships are there homez, so the entire return trip idea duznt exist.
