As soon as there is talk about aliens the conversations stop.
And I can understand why.
Ordinarily people are pragmatic and are looking for information that is actionable. We want information that is practical.
At this point even if you personally saw a UFO and were personally convinced that it was a UFO - what can you do with that information.
The aliens aren't talking. They aren't telling us what they are up to. They aren't helping our arthritis or allergies.
Until they communicate to us exactly what they plan to do it doesn't change our lives at all.
You could have a close relative who is one of the richest people on earth and if they don't seek you out it means nothing.
That's why confirming evidence of aliens fades quickly.
We all have too much on our plate.
At best we put it in the same category of ho hum well that's interesting. The tallest mountain on earth is under water- ho hum that's interesting. A 10,000 ton asteroid may hit the earth in 80 years - that might be interesting if I live that long.
