>>3395 very unlikely anything survived even if there was, any liquid water would be far too salty and would be deep underground. Venus is far more likely to have life, plus it almostly definitely had water oceans too in the past.

If there is life on Venus there is also probably life underground on Mars and in the Titan's water.

Would be interesting how this changes our understanding of the Universe if we find evidence that life is simple enough to produce that not only is there another inhabited planet in our own solar system, but it also exists in much more hostile conditions than Earth ever presented

The signals we've sent from Earth have almost entirely dissipated before they even leave the greater solar system because of the distance and amount of matter scattering them. Unless you are purposefully beaming a focused signal in a certain direction there's no reason to think it would be visible.

>>3417 >>3419 >>3416 There's also multiple potential Great Filters (assuming the theory is correct). The formation of microbial life probably isn't it, since it seems to have formed on Earth very early in our history. The real leap in evolution that kickstarts increasing complexity seems to be eukaryotic and multi-cellular life. It took around a billion years for life to emerge on Earth, followed by ~2.5 billion of simple microbial life. In the last billion we've gone from prokaryotic cells to human civilization. This seems to point to the transition from single celled to multicellular life as the real hurdle.

>>3452 if this is real (again, i'd guess its not) there is a good chance its related to earth life. there are a pretty large amount of meteorites that were originally from mars before getting blown off into space by large asteroid impacts and then hitting the earth without being melted or anything, there is a good possibility that the same thing happened with the earth and any bacterial spores or whatever that survived might be able to survive on venus, or even the other way around
https://arxiv.org/abs/1608.00706 venus could have had oceans up until a few hundred million years ago so its not completely impossible
still this is probably due to some weird volcanism or something, iirc there was something similar to this with methane being detected in the atmosphere of mars but now the general consensus is that it is from some weird reaction between subsurface water, olivine, and co2
