Well, very interesting. I read this new report expanding the Drake equation.
We should find extraterrestrial life within 60 light-years if Earth is average, professor claims,
In 1960, while preparing for the first meeting on the Search for Extraterrestrial Intelligence (SETI), legendary astronomer and SETI pioneer Dr. Frank Drake unveiled his probabilistic equation for estimating the number of possible civilizations in our galaxy—aka The Drake Equation. A key...

My note, here is a big problem with this new model for life in the MW near Earth. “The causes and commonality of abiogenesis is one of the least-understood scientific pursuits, mainly because it is so data-poor. Armed with only one example (Earth and terrestrial organisms), scientists cannot confidently say what combination of conditions is necessary for life to emerge.” My note, science has never observed non-living matter evolve into life and Charles Darwin acknowledged this problem in his 1882 letter.

My note, “If simple life is abundant (fast abiogenesis), it is also old, as it would have emerged more than 8 Gyr ago in about one third of all life-bearing planets today.” This new model depends upon *fast abiogenesis* working in nature. Consider what Charles Darwin stated in Origin of Species about the origin of life, his 1871 letter using a warm little pond, and 1882 letter where nothing worthwhile had been presented to show nature creates life from non-living matter, and certainly not *fast abiogenesis* at work in nature let alone on exoplanets far away.
