As of now (2025), there is no reliable evidence to suggest that extraterrestrials have visited Earth.
— "Where are they?"
N = R* × Fp × Ne × Fl × Fi × Fc × L
N:The number of detectable extraterrestrial civilizations in the galaxy
R*:The rate of formation of stars in the galaxy
Fp:The fraction of those stars with planetary systems
Ne:The number of planets, per solar system, with an environment suitable for organic life
Fl:The fraction of those suitable planets whereon organic life appears
Fi:The fraction of life-bearing planets whereon intelligent life appears
Fc:The probability of a civilization emitting detectable signals
L:The lifespan of a civilization
The Drake Equation helps us understand the probability of extraterrestrial civilizations existing. Galactic Simulator 2: Stargate implements all the components of this formula.
The Great Filter is the idea that, in the development of life from the earliest stages of abiogenesis to reaching the highest levels of development on the Kardashev scale, there is a barrier to development that makes detectable extraterrestrial life exceedingly rare. According to the theory, Galactic Simulator 2: Stargate defines the following Great Filters (evolutionary stages):
Civilizations have a probability of failing at various stages of the Great Filter.
