The fact that since the same elements that this solar system is comprised of, are the same elements that make up all star systems, you will need to explain to me what is so unique about Earth that only it was ever capable of giving rise to life since time began?
Well, It's stable main sequence solitary star sets it aside from the vast majority of star systems right off the bat, most are multiple chaotic systems, and/or too hot/short live cold/small
Habitable zone obviously
Rotating suspended iron core creating a magnetic field to protect from solar radiation
perfect proportions of land, water, atmos, tectonic system and a vast array of parameters necessary for life as we know it
One single vast stabilizing satellite... creating a perfect balance of climactic stability yet diversity and crucial change, tides etc- this alone may be one of the greatest idiosyncrasies that made complex life possible on Earth.
The whole system remaining stable for billions of years, yet with near perfectly aimed/weighted extinction events- particularly the one which made mammal dominance possible.
Just to name a few. The list grows ever longer the more we learn, but the number of stars does not. Crunch the numbers, and it's not looking too promising for ET.
