It is then obvious that, assuming these low-mass stars provide a not too dissimilar environment for Life compared to our Sun, the relative probability of life-emergence has to peak in the very far future. This is the main result of Loeb and collaborators. Note they do not tell how many planets hosting life are present at a certain time. They just calculates the relative probability as function of time, which turns out to be much higher in the distant future than it is now.   As the authors point out, ``The question is then, why do we find ourselves orbiting a star like the Sun now rather than a lower mass star in the future?''
