Alien 'life'

Octopi aliens

Came across this -debunking the idea, but worth mentioning. Anna Livia (talk) 12:03, 26 April 2022 (UTC)

Water water everywhere

'For whatever reasons' thought of the couple of sci-fi where 'the aliens' came to take Earth's water.

Surely if the aliens have the technology to come to Earth they could set up in their solar system's equivalent of Oort Cloud and Kuiper Belt zones, attach 'rockets or other space moving technology' to a sufficiency of protocomets, transfer them to planetary orbit, process them to remove 'assorted chemicals (space-created organic materials etc) and stones' (which can then be otherwise used) and then send the water planetwards? No problem with natives complaining about the removal of water and having to deal with Earth's gravity. (Can someone else come up with the details of the processing facility?)

i wonder what any of you can make of this. ^{— Unsigned, by: John woo / talk / contribs}

This article is self-published by one of the journal editors which is often a red flag in science publication, though the journal itself reports it goes through a double-blind peer review process so maybe that isn't a problem in this case. Regardless the evidence in question is pretty weak. Microorganisms can end up the stratosphere for all sorts of human caused reasons given the number of things we have sent up there and beyond. Just because the author in question cannot recognize the organisms as having any similarity to any terrestrial organisms doesn't mean that the organisms in question are by necessity extra-terrestrial in origin. Only that it doesn't resemble what we have discovered so far on earth. So as evidence it may suggest extraterrestrial origin, but the evidence in question does not logically entail it and cofounding factors have yet to be sufficiently ruled out. .

Maybe it's in there somewhere, but I can't find the bit where they actually demonstrate that the artifacts actually are, in fact, biological (rather than looking biological). I see no talk of DNA for example.

I think the article falls into "argument from ignorance" territory when it makes the dramatic claim: "We don't know where they came from therefore they are alien". Rather than the more honest "We don't know where they came from".

I note that the article dates from 2015. If the article is reliable it is perhaps surprising that there has not been more reaction from the scientific community (who would know a lot more than me) in the intervening eight years.

That's not to say they haven't discovered alien life. I'm just not (yet) convinced by this.Bob^{"Life is short and (insert adjective)"} 06:13, 26 August 2022 (UTC)

It's definitely not conclusive - they do accept a possibility that it might have a terrestrial origin. I'd definitely want to see a more thorough analysis than just sticking it under an electron microscope. Isotopic analysis (comparing ratios of isotopes and seeing if they match terrestrial samples) would provide some evidence of an extraterrestrial origin, as would searching for DNA and other molecules. Events such as volcanos can eject matter into the stratosphere, so it doesn't seem too surprising to find some organic matter up there. --Annanoon (talk) 09:40, 26 August 2022 (UTC)

Looking at the lead author's publications he does seem to have quite a thing for extraterrestrial life and panspermia. I see that his current project is: "First complete (integrated different fields of studies and sciences) applied study of Astrobiology which analyses/tracks the entering event of COVID-19 virus of Outer Space origin onto planet Earth and outlines main confirmations of Panspermia paragim."

Covid-19 came from space? Who knew?Bob^{"Life is short and (insert adjective)"} 13:23, 26 August 2022 (UTC)
