The atmosphere of Jupiter is extremely complex and not at all logical...
Within the regions of gas, the temperature varies in the layers of Jupiter's atmosphere. From the surface to about 30 miles (50 kilometers) up, the temperature decreases as you ascend, ranging from minus 100 C (minus 150 F) to minus 160 C (minus 260 F). In the next layer, the temperature increases with altitude, returning to up to minus 150 F again. At the top of the atmosphere, temperatures can reach as high as 1,340 F (725 C), over 600 miles (1,000 kilometers) above the planet's surface.
Note the surface is defined as being the altitude at which the air pressure is equal to the surface of earth... there is no solid structure there to stand on, so 1,000km above that the temperature is hotter than an oven... with layers below that ranging from seriously cold to just really really cold.
Assuming noncarbon based life is possible, such as silicon life. but I think that's dubious.
In a galaxy far far away a rock face and a coral reef might be having a discussion about whether carbon based life forms could develop...

But that's designed by life; it couldn't have appeared naturally.
Does that matter?
Ask a Christian and they will tell you a higher power created life on earth... what if it was an alien?
There were a lot of very specific events that created earth and set it up the way it is to make it suitable for humans... whether it was the early impact that created the moon to stabilise our rotation and create seasons, or the 6... count them... 6 mass extinction periods needed to create the planet we live in today... did the water on this planet come by comet, or did all the solid planets have lots of water that has been blown off into space by the lack of atmosphere and the solar wind and lack of radiation belts...
Even useful potshots of large rocks from space to get rid of the dinosaurs...
It has been a really lucky run, but then you could argue it hasn't seemed to happen anywhere else that we can see, so it was pretty much a case of it not happening most of the time in most places... ie it wasn't a case of us being lucky, more of a case of we are here because it happened.
Russell suggested that had nonavian dinosaurs survived, eventually a dinosaur such as T. formosus might've radiated into the niche currently held by man. And I'm not sure that mammals would've remained small and unimportant had nonavian dinos persisted. Some of the lineages that led to modern mammals already existed prior to the K-Pg. IF Purgatorius (like Protungulatum)was already present in latest Maastrichtian time, so that dino dominance didn't prevent initial primate radiations, maybe later ones would've gone the same way even had dinos, not big mammals, been the main challenge. Just as some primates eventually became terrestrial and overcame the dominant terrestrial megafauna (mammalian) the same might've happened had big dinosaurs lasted.
Well how do they explain all the massive dinosaurs that lived in the sea disappearing too... why were they all wiped out as well?
Perhaps the comet story is just a cover for aliens that came and wiped out all the large animals in a predator type frenzy, to leave the planet open to develop smaller but smarter animals... maybe they are due back for round two...
