The problem is that the term "yet" represents an open-ended commitment that can only end when incontrovertible evidence of intelligent life outside the earth is found. The universe is so vast that there's no way every corner of it can possibly be searched ... so "yet" goes in (forever, in theory) unless and until something is found.
On the other hand, there's a perfectly reasonable bias that has nothing to do with faith and everything to do with scientific/mathematical realities. The longer I look for something without finding it, the less likely it would seem that it exists at all. That's not a matter of faith. It's a matter of empirical evidence.
That said, I don't think this discussion of life elsewhere in the universe is relevant to the "phenomenon" under consideration lately (stemming from sightings of tic-tacs and other craft by the Navy).
It is premature to suggest that there is some lifeform behind these sightings. They may be nothing more than natural phenomena or even directed by some kind of machine from sources unknown. Or they may be some kind of projection created by an adversary.
Pondering the imponderables automatically leads to the formation of biases and premature conclusions.
They actually prided themselves in their materialist view of reality.
Things have changed.
Some scientists are now suggesting that the universe itself is conscious. For example:
One of the leading minds in physics, 2020 Nobel laureate and black hole pioneer Roger Penrose, has written extensively about quantum mechanics as a suspected vehicle of consciousness. In 1989, he wrote a book called The Emperor’s New Mind, in which he claimed “that human consciousness is non-algorithmic and a product of quantum effects.” SourceSuch stuff is way over my pay grade.
