It would not be surprising if ancient life did exist on Mars, since impacts would likely have sent life back and forth between Earth and Mars (and possibly Venus).

For the same reason, the existence of ancient life on Mars would not show that life is likely to arise on Earth-like worlds, since one could not conclude it was an independent event.

Sending a microscope is easier said than done. Many natural structures can look like bacteria, and vice versa. If there's more complex single celled life then we might see stuff swimming around but that's considered unlikely close to the surface where there's a decent amount of solar and cosmic radiation. If complex life does exist it's probably deep underground or in caves and lava tubes where we can't reach it yet.…

What reasons do you think exist that lead you to believe Earth is special for having evolved complex intelligent life?

The Fermi Argument.

I see this author has "12 honorary degrees and is an Officer of the Order of Canada". And CBC is Canada's government-funded national public broadcaster. But it's hard to take them seriously on any particular details given that their article, up for 8+ months (!), mis-describes H.G. Wells' War of the Worlds as a story of the Earth "invaded by benevolent Martians". [emphasis mine] It's a seminal work of scifi, which po…

It was obviously meant to read 'malevolent' and got spell checked to death. That sort of thing happens to everyone, and I'm not sure why you mention the authors credentials like they're a bad thing?

Because honorary degrees are not credentials.

Someone should look into the author and/or editor.

Probability seems high they are martians trying to whitewash fictional history.

Tangential, but really looking forward to what Europa Clipper[0] finds in its flybys. The delay in communication makes ambitious manoeuvres challenging - perhaps advances in AI (and by extension robotics) helps build much more autonomous space rovers. This could enable us, for example, to evaluate the samples by sending wet microscopes with the rover itself. [0]: https://science.nasa.gov/mission/europa-clipper/

Tangential to your tangential: The era of AI makes me realize that if we ever get visited by aliens: it will probably not be actual aliens -- just an AI probe. And the idea of it really intrigues me. Imagine some LLM that is many generations ahead of Fable -- but from a different world -- visiting us. It would be amazing.

we may have found that AI a while back in roswell, along with some Nitanol foil and berylium "I" beams

Weak evidence for life, at best. Which is why exploration continues, to search for stronger evidence. If irrefutable evidence of life were found it would open up many new avenues of exploration and research that would need funding, with strong justification - much stronger justification than currently exists.

I don't think it was weak at all. We got two positive results from the Viking landers and then tried to explain them away. There is a lot of circumstantial evidence, which combined builds up a case. The public believe we should be looking for cities and skeletons, when in fact we should be looking for extremophiles. It is possible that some of these are due to cross-contamination within the solar system (before human…

Two positive results that had non-biological explanations and a lack of any other significant evidence. Extreme skepticism is warranted.

I wouldn't expect it to be less murderous than the aliens themselves. That wasn't my point at all. I'd expect it to contain all their knowledge and be able to live "forever". But I generally wouldn't expect aliens to be "murderous" at all. Why send a group or probe lightyears away just to kill or enslave a primitive species? If they have the ability to do that, we wouldn't really have anything of interest for them.

At most points in time resources are scarce and not all life can be supported. At those times beings with a tendency to say “them” will give way to beings who most strongly assert “us”.

Comments like yours make me think that sci-fi shows (and a lot of literary sci-fi) like Star Trek did a grave disservice to our conception of advanced spacefaring civilizations. They were always focused on alien planets, assuming that once a race was able to travel the stars that they would still chain themselves to a gravity well. It's like imagining an industrial society where everyone still lives on a farm like their agricultural predecessors. Nothing makes sense if you start with that assumption, living space becomes scarce, utilities are hard to provide, travel is cumbersome and a lot of things simply aren't possible. The same way that industrial societies urbanized and concentrated in cities, spacefaring civilizations will move to orbital structures that allow them to design their environments. These may be located near planets the same way cities are located near important geographical features but there will also be many that are only in orbit around their host star. Habitable worlds will become the equivalent of bucolic countryside estates or national parks. Most industry will be located around lesser gravity wells such as moons or minor planets where mined materials are easy to transport to orbit and there aren't biospheres or atmospheres to worry about. It would take a long time and a lot of expansion to exhaust the materials in a solar system.

Some of the more out there UFO theories postulate on these lines. An idea that rather than say send an explorer of your own species to some planet with all the needed life support, you use genetic engineering to create a worker bee essentially, already tailored to perform whatever function under whatever environmental conditions are present at the target planet. You may even be able to build this species using genes already present at the host system in some reduced to essential components fashion like an engineered plasmid in the molecular biology lab. This would also double as camouflage keeping the worker bee genetics separate from genetics found in your own planet or star system, making them appear endogenous to the target planet instead.

It's hard to take seriously someone who dismisses the (factually correct) content of a popular science article just because of a typo that has no bearing on that content.

Because honorary degrees are not credentials.

But that's obviously not a reason to treat them as a bad thing. It's also not entirely true ... he was awarded those honors because of the quality of his science journalism.

FWIW, I think @mapontosevenths is wrong to say that @gojomo's mention of the honorary degrees and being an OOC was "like they're a bad thing" ... their "But it's hard ..." indicates a conflict between those "credentials" and the typo that gojomo makes way too much a deal of.
