Aliens are nonexistent for anyone who even remotely understands the cascade of chemical and evolutionary conditions needed not only for the formation of life, but its evolution to the point of intelligence. There is no overarching process guiding any of it, each mutation is a random event and the survivability of it to the point of procreation is unlikely in most instances; evolution is not predestined, it is post hoc selectivity that favors survival. Calculating the joint probability of all the unlikely events from the formation of the first bacteria to the fluke that allowed our progenitors ages ago to shift the jaw forward to allow for a random brain, is beyond immense, beyond the number of atoms in the universe or possibilities in a game of chess. 10^800 or more. Each individual member of a species through sexual reproduction is against 200M+ other potential, compounded, the genomic probability over millennia and eons manifesting in the human species is so remotely improbable that to expect it to happen again is delusion. The Drake equation fundamentally misunderstand evolution and assumes life to always lead to some greater outcome, an assumption that is baseless. If humans were exterminated, it is unlikely that any species from now until the earth's end would ever again manifest a pattern of traits resulting in intelligence even remotely approaching our own.
