Reports of signs of life on Venus may be exaggerated. Imagine that - NASA scientists exaggerating the possibility of extraterrestrial life.

It's all about the discovery by spectrographic analysis of a gas in the Venusian atmosphere which indicates the presence of something called "phosphine". That only occurs naturally on Earth as a by-product of anaerobic metabolism (life). But what is being ignored is that phosphine is fairly easy to create in the laboratory by inorganic means.

There are other often organic molecules which are produced by inorganic means. Amino acid molecules, and complex hydrocarbons have both been detected in astronomical observations (comets) which are considered the building blocks of life. But they did not arise from metabolism, but chemistry.

Venus is radically different from Earth. Venus is like Earth would be if there was no crust and the raw heat of the mantle and core were diffusing constantly into the atmosphere.

Heat generates very accelerated chemical reactions, so the possibility that the phosphine is being created by some previously unknown mechanical process is very high.

If they find one of the chlorophyll isotope associated exclusively with photosynthesis, then I will become intrigued.
