NASA finds Titan's lakes may be creating vesicles with primitive cell walls

This feels very cynical, but what incentive does NASA have to do research showing alien life is not very likely in our solar system?

Regardless of incentives I think this is some of the most important research they should be doing. As a species we need to get a better understanding of the probability of life on other planets and therefore a better understanding of fermi's paradox in case the dark forest theory is correct. So if NASA has an incentive to discover potential pathways for extraterrestrial life... great!

A non-trivial faction of our government has been teasing knowledge of some sort of non-human intelligent lifeform (that word isn't considered precisely accurate) on EARTH.

This isn't some crackpot theory, they've been having congressional hearings about it and congresspeople say it's real. You can think they are or aren't credible or being lied to, but, if congresspeople are part of or victims of some sort of psy-op with vague parameters and goals, our entire system of government is basically forfeit.

I realize this is difficult to deal with but it's a pretty well-established fact at this point.

We don't need to go anywhere for this information.

Making the analysis harder is the fact that those politicians are either exceedingly stupid or brazen liars, or both.

Credible non-politicians, people in sensitive CIA or senior military leadership have consistently made these claims. They may all be liars, but none seem particularly stupid.

One problem is that we haven't gotten a "UAP Snowden". Such a person has seen a serious chilling effect.

Or maybe there's been "no UAP Snowden" because there's actually nothing to leak.
