Earth and the solar system are related through their shared context in astrobiology and the Fermi Paradox, where Earth is compared to other environments within the solar system regarding life-supporting conditions [1], [2], and [3]. Furthermore, the search for extraterrestrial life and intelligence frequently contrasts the lack of evidence on Earth with the broader search across the solar system [4], [5], and [6].

referenceMilan Ćirković categorizes the Fermi Paradox into three levels: ProtoFP (the absence of extraterrestrials on Earth is incompatible with our assumptions), WeakFP (the absence of evidence of extraterrestrials in the Solar System is incompatible with our assumptions), and StrongFP (the absence of any evidence for extraterrestrials anywhere).
