And yet as of now the odds of there being microbial life on Venus and not Mars is much higher.

Sadly no space comrades evidence yet.
At least the phosphine seems to prove in a way that it's very likely that there is life in the high ups of Venus' clouds. But as other anon said, it's pretty difficult and there are more close plans to go to Mars than over there.

Great Filter is a meme. 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.

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.

David Graeber thought the Great Filter might be "simulationism" or the tendency to isolate and focus on our drives instead of follow them to the "logical" conclusion. E.g. we have a drive for sweetness because eating fruits is good, but we have created sugary food to simulate what we evolved to want. Another one is that we like to make science fiction to entertain us and scratch the itch for technology and innovation.

DNA is actually kind of mysterious because we don't actually need the 4 bases. 2 would be enough. So you could have a DNA with only 2 bases or with a different 4 or more than 4. There might also be a different way of solving the same basic problem of storing instructions for biological processes.

uigha that site is reddit-tier. there are multiple different ways phosphine can be generated by natural activity, for example the reaction of metal phosphides with water or an acid (venus has sulfuric acid clouds and a lot of metallic iron in meteorites has a decent percent of phosphorus dissolved in it as nickel/iron phosphide). still interesting, could tell us about the geology there and shit but its probably not life. even if it is its only gonna be bacteria.

this sounds dumb as shit at first but once you actually start reading about it its basically the only way for people to expand off earth, you can build ones miles in size with just steel or aluminium and spin them to fake gravity with centripetal force so you can make them reasonably earthlike in terms of someone living inside one in terms of "gravity"/air/water. plus due to how easy it is to exploit solar energy in space manufacturing costs for the raw materials needed to build them would be much lower than on earth

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
