Are you saying Wei, that there is a flaw in this logic?

Sorry for the hair-splitting and thank you for a good post

There has been a huge amount written about the Fermi Paradox (why are
there no aliens) over the years, and I don't want to reiterate that here.
You can come up with scenarios in which intelligent life is common but
where they just aren't visible, but IMO such explanations are not very
natural. Ins
Why don't we see Others?
I think the anthropic principle neatly explains both scenarios: why we're
here, yet nobody else seems to be.
If life nucleation density is arbitrarily low (e.g. 1/visible univers) we
still wouldn't fail to observe our existance.
It is also worthwhile to mention that the

This was first expressed as the Fermi Paradox, i.e., where are the aliens?
As our understanding of technological possibility has grown the problem
has become even more acute. It seems likely that our descend
