We don't know if it wasn't inhabited and we don't know if it is currently uninhabited.

Of course, which is why I said "probably".

Well we know that it's not inhabited by 'life as we know it' right now at the very least. Because that's just not going to survive there. It'd be a pretty far stretch to come up with something that can.

  There is a habitable zone on Venus in the upper atmosphere, so it's not completely out of the question.

    That's been thoroughly debunked.

      Note that a habitable zone does not necessarily mean there's any life actually there. You are probably thinking of the reports last year of phosphine in the upper atmosphere where the quantity turned out to be overstated by a significant amount. On the other hand, there is a sweet spot in the Venusian atmosphere where the temperature is low enough and the atmosphere provides enough protection from solar radiation that microbial life could conceivably survive (which is not the same as saying there is any life there); there are certainly plenty of Earth microbes that live in environments just as inhospitable if not more.

        Except, there's no hydrogen in Venus.

        There is hydrogen on Venus. Very little. Some hydrogen chloride and hydrogen fluoride.

        I'm just gonna leave this here. https://en.wikipedia.org/wiki/Venus_atmosphere https://en.wikipedia.org/wiki/Venus_atmosphere Hydrogen chloride 0.1–0.6 ppm Hydrogen fluoride 0.001–0.005 ppm

        Like I said, it's very little, but that's not none.

        It's none :D If you knew anything about chemistry past checking wikipedia, you'd just call it none.

Venus is almost guaranteed to be currently uninhabited because that planet has almost no hydrogen in it. Almost all "complex chemistry" that we know of involves hydrogen. So to those people who say "but but but that's just life as we know it". No, it's also chemistry as we know it.
