Providing of course we are talking about human life,not life that evolved to thrive in that atmosphere.
Interesting speculation - of course there is no sentient life-form even remotely similar to something like that. According to what we know of the prerequisites for life, among them is shelter from strong EM/hard radiation (especially higher-energy). See, organic molecules are fragile. They break down rapidly when exposed to things like UV-X-Gamma Ray/nucleon particle ("hard" neutron/proton) radiation bombardment.
So in addition to liquid water, one could reasonably add "protection from harsh radiation" to the requirements for organic life (cell homeostasis). Also all higher-order living things have some sort of RNA or DNA, (another delicate organic molecule) which is subject to destruction by harsh radiation/corrosive chemicals
Even if radiation itself may not be lethal to cells, the by-products of harsh radiation in the form of toxic/corrosive chemicals, are. For instance, even on a fairly Earth-like planet like Mars, where liquid water existed for a long time in large amounts, the lack of a magnetosphere/ionosphere to screen out harsh radiation causes the planet to be bathed eternally in high-energy radiation which creates the poison hydrazine (created when chlorine molecules are bombarded by UV radiation). Virtually all of the water-ice on Mars is likely poisoned with lethal amounts of hydrazine.
My own feeling is that any extraterrestrial life-forms out there capable of knowing we are here, regard us with indifference. Especially if it's a technological culture thousands, millions or billions of years older than our own.
Can we even imagine the sort of technology involved in efficient interstellar travel? My guess is that a culture such as ours would be about as interesting to a Mature Culture with trans galactic traveling capability, as a pond full of trout is to us.
