Biosignatures do not equal life. Assuming the presence of phosphine is confirmed, the detection of a single biosignature does not mean life has been found on Venus. It's ok to be excited by the unknown, though!

Ah ok: my apologies!

Sorry about that: I misread the tone over the Internet, and thought you were making an anti-space argument.

Well, anyways... my argument above applies to other people who are antispace and lurk here (rather than you), so I'll leave it up and not delete it, unless you prefer I delete since I misunderstood you, then just let me know.

But yes, you're right: we might not understand this chemical reaction process for a long while.

But one way to check, might "simply" be to take a sample of Venus' atmosphere, especially around the areas with those wavering dark shapes, which some scientists have wondered might possibly be alien-microbial colonies in the clouds.

And of course whenever one invokes aliens as an explanation, that's quite a claim, so we're going to really have to send a sample mission to Venus. (Luckily such an atmospheric sampling mission may not be as difficult as it sounds, and certainly doable with current technology, since we need not dive deep to sample the interesting portions of the atmosphere.)
