Examples of abiogenesis,
H2O, two fundamental chemical elements producing a fluid substance which has many potentials including being "necessary" in the formation of living organisms.
Just two chemicals, abundant in the universe.
Carbon,
https://en.wikipedia.org/wiki/Carbon
Three elements which are "necessary and sufficient" for being used during the emergence of "living" things.
All living things have at least these three elements as common denominators in their patterns of expression.
As all three elements are abundant and extremely versatile in bonding abilities, an exponential multiplier creates a near infinite amount of variety, including "living" varieties, dependent on further evolution of complex patterns from other available chemicals .
