I'm a PhD candidate studying Mars, happy to debunk any structures you can supply.

PHD won't save you here. I am not talking about Face on Mars either Literally pyramids and megastructures with uniform and clear patterns of engineered structures. There's really nothing you can say here to convince me otherwise. There's zero chance of a large pyramid structure with accurate math proportions and geometric consistencies occuring by "chance" I don't know about other stuff you are speaking of but there'…

How does f430 know this and people who study the Moon and Mars as a profession do not know this?

The great filter is that tech is to easy, but self-awareness and self-discipline is hard. So life presses onwards, demanding exponential energy density from tech, to not be forced to limit itself and self-discipline itself. Thus ever more potent tools are handed out to avoid confrontation with the "overcome" animal nature - and once that equation reaches the end of the line (easy energy and resources exhausted), a ne…

There could be civilizations out there that never developed aggression.

becaue the people who study Mars professionally will never ever be allowed to disclose or deviate beyond the tiny bubble of academia Mr. Cohen.

after all, they are just another subordinate of a massive defense industry umbrella.

What happens when we'd put some microbes there now?

I've been curious about this recently actually. What are the downsides of "seeding" a plant with life to study how it evolves?

Evolution takes a long time. And there aren't many (any) environments that we've identified and can reach which are conducive to the sort of life we know about. Also it'd be a bit presumptuous for us to colonize a hospitable planet for our own experimentation.

But it's an interesting question. In fiction, I can recommend Adrian Tchaikovsky's Children of Time, and sequel Children of Ruin.

Imagine if an alien lifeform had terraformed earth this way. We would not have existed. (There is a hypothesis that life may have been introduced this way to earth, known as the Panspermia Hypothesis https://en.wikipedia.org/wiki/Panspermia )

There are so many chance events that could have gone differently and we would not have existed.

If not for an asteroid, the earth might still be populated with dinosaurs. Would they have evolved to our degree of intelligence and civilization? Who knows?

I don't understand the excitement for finding life on Mars. I personally really, really hope we do not find life on Mars. If we find even the most basic microbial life, NASA is going to shut down all future exploration in the interest of Martian planetary protection. China and Russia probably won't, but the US will cripple itself (again) out of caution. On a more existential level, finding life elsewhere in the solar…

Personally, I don't believe in the great filter hypothesis. The universe is incredibly vast enough entire civilizations can likely go through millions of years of births and deaths without ever having contact with another alien life form. Humans have a huge bias to feel "special". We've only been broadcasting radio waves for a few decades now, and even that would just be lost in the background noise at large distance…

I don't think this gives appropriate weight to exponential growth.

If humans are ever able to leave the earth and even theoretically establish permanent habitation, it's unthinkable that no other civilization has done so.

Billions of people were just asked to spend over a year locked down in isolation, and most did it voluntarily without reverting to tribalistic warfare (threats on fringe social media platforms notwithstanding). We've also in modern times seen what happens when famine strikes. Mostly people just suffer quietly and die.

We probably have done this already, with the man made machines that we had sent. Although the NASA tries to sterilize the robots/rovers, I doubt that they can kill every bacteria and some of the bacteria are known to somehow survive when exposed to space as well.

Earth bacteria require liquid water (amongst other things). Thus far none of the rovers have landed in a lake, so it's unlikely that earth bacteria will be spreading any time soon.

Even so the galaxy (let alone the universe) is huge, and faster-than -light or extra-dimensional travel is probably impossible. Contact with another civilization is extremely unlikely even if life is abundant in the galaxy.

Assuming this is even in good faith, can you link any images or data of these supposed structures? I spend hours a day examining HiRISE/CTX imagery and have never seen anything like you're asserting.
