I can't see how bacteria could possibly evolve in the atmosphere but Venus is believed to have once had oceans.

Could also have been brought to the upper atmosphere by a piece of earth blown off earlier. Would be epic to find it might even be shared earth DNA-based life. But it's most likely just unusual high temperature processes in the Venusian atmosphere.

The question I have is how they could get access to micronutrients up there. On Earth, there's dust blown from dust storms, etc, but my read on Venus is that there's not a ton of circulation between the hellish surface and the upper atmosphere.

  Volcanic activity throwing nutrients up there is what I've read.
