There is a layer in the atmosphere of Venus where water can exist at a triple point. There is a ton of carbon in the air there as well. The question becomes... Can long carbon chains form in this zone? can they reproduce? We know that there are bacteria that can use sulphur as an energy source so from what we know about life on earth, this is a possible zone for living things to exist.

If there is living stuff in the clouds of Venus, however, and it has earth dna structures and amino acid chains, we have to figure out if life started once in the solar system and spread, or did it start from zero on earth and Venus?
