Of course, it's been my impression that these 'discoveries' fall by the wayside and get forgotten, but by then the newest 'discovery' has taken the spotlight...and so on
Most scientific work doesn't result in a shiny new edifice of discovery; and although they don't dazzle like the major breakthroughs they pave the way toward, complete failures and almost-successes are necessary steps.
I haven't failed, I've found 10,000 ways that don't work
- Thomas Alva Edison
A present problem in science is that negative results are often not published. Edison worked at physical projects simple enough that he could make and profit from 10,000 failed attempts; scientific challenges have become too complex for that kind of brute force, one scientist approach.
These are the 'discoveries' that end up in magazines and newspapers enough to give the public the impression that scientists 'pretty much know' that life originated by natural causes.
Well, if "pretty much know" is the epistemic bar, I'm content to say I pretty much know that life originated by natural causes.

Re: Good Question
I know you just want to discuss conspiracy media theories with ringo
I'm suggesting your critique fails because it's quite sensible to pretty much believe that life originated from natural causes. So it's not a sly media con that creates that impression: it's reality.

And may I remind you, I have the utmost respect for scientists in general.
Good.
Then you'll certainly understand why I feel that I pretty much know that life originated from natural causes.
Tens (hundreds?) of thousands of those scientists whom we both respect have scrutinized the world from the subatomic scale to 14 billion years away, and they have yet to uncover any unnatural or supernatural causes.
So if you hear, regularly, stories that suggest scientists are hot on the trail of a mechanism by which DNA-life life could have emerged (a better word, I think), that's because they are. The growth rate of our scientific command of the mechanisms of DNA-based life is breathtaking. Even at the threshold of creating synthetic organisms, we have found no need for magic.
So, anyway, why wouldn't anyone feel confident that life originated from natural causes? What other kinds of causes have we discovered?
