What are the different types of extraterrestrials (ETs) or alleged alien species? (Alien Archetypes)
The observable universe contains hundreds of billions, and possibly trillions, of galaxies, with astronomers estimating that planets are extremely common throughout the cosmos. That immense scale has inspired endless curiosity about whether intelligent life exists elsewhere, what extraterrestrials might look like, how they might behave, and whether humanity has already encountered them in some form.
From ancient sky gods and modern UFO reports to science fiction and spiritual beliefs, countless ideas have emerged about intelligent beings beyond Earth. These alleged extraterrestrial species, often called ETs, have become deeply woven into popular culture and continue to spark debate, imagination, and speculation around the world.
