From one of the scientist's personal site: "I found that, if detected on a rocky planet, phosphine can only mean life." For one, this assertion seems too certain to be scientific. That they attempted to create phosphine using a non-biological method and were unable to do so does not appear to be proof of anything except perhaps it does indicate likelihood. However, we shouldn't be fooled into believing that nature's creativity does not often exceed our own, even our brightest minds. Jupiter and Saturn are able to produce this molecule and while they don't fit the assertion's limitation of "rocky planet"...Venus certainly has many unique characteristics that may produce this molecule. Professionals get things wrong, too. As Feynman said, "you must not fool yourself and you are the easiest one to fool."
