Eric von Däniken with his ancient astronauts was far from the first to speculate about ancient aliens, though he made the notion very well-known with books like "Chariots of the Gods?" It goes all the way to Helena Petrovna von Hahn Blavatsky, the inventor and plagiarizer of Theosophy (Blavatsky on Ancient Astronauts - Jason Colavito).

Carl Sagan himself speculated about that. Around 1955, in a very formal sort of restaurant, he once asserted "I say to you, Jesus was extraterrestrial". In 1966, he published more speculations about that in his coauthored book "Intelligent Life in the Universe" (Chapter 33, "Consequences of Direct Contact").
CS first tries to estimate how often the Solar System has been visited by interstellar travelers on survey missions. Doing so requires a lot of hand-waving, so I don't think that anyone has good numbers on that.
He then gets into accounts of contact, briefly dismissing recent claimed contacts. Like by a UFO contactee who was put on trial for fraud, with CS testifying in that trial.
Then some Earthlings' contacts with some other Earthlings. Like some Tlingit people who had remembered being visited by La Pérouse's expedition a century earlier, though in mangled form. La Pérouse's ships were turned into black birds with white wings, for instance. An old man went aboard one of them and discovered that there were fellow human beings on board.
CS decided on some criteria:
Then what are likely depictions of some people in ritual costumes.
He then gets into the issue of the Sumerian Apkallu. He starts with three surviving accounts, from historians Alexander Polyhistor, Abydenus, and Apollodorus. They all reference a contemporary of Alexander the Great, the priest and historian Berosus. Oannes and other Apkallu looked like fish, but with a human head inside the fish's head and human legs coming out of the tail. They'd be on land during the day, and in the water at night. They were described as "animals endowed with reason", "beings", "semi-daemons", and as "personages", but not as gods, a description that suggested ET's to Carl Sagan.

One can be skeptical of stories like that, because they seem like Just So Stories to explain how their tellers acquired technologies that they have no memory of inventing. Something very likely for technologies several centuries or millennia old.
Carl Sagan is very cautious here, unlike Erich von Däniken and most other ancient-alien believers.
Then CS gets into other possibilities, like some monitor of Earthling technology that would radio home if it detects evidence of sufficiently advanced technology.
Then what ET's might want with us. Certainly not natural resources, because they could get all that stuff much closer to home. Consider "V", in which the Visitors want to steal the Earth's water and eat us. That is absolute nonsense. Water is H2O, and hydrogen is the most common element in the Universe with oxygen the third most common one in our Galaxy. If they can't get water from comets in their system, then they can get it from comets in ours. As to human flesh, they'd have to be some sort of weird gourmands to find human flesh anything special. Why that and not (say) octopus flesh or caterpillar flesh or moss or bread mold? Also, as meat animals, we are very bad. Though we are very big by animal-kingdom standards, we grow slowly and reproduce slowly by animal-kingdom standards. Most livestock species beat us in growth speed, and some can easily beat us in reproduction rate. Your average domestic sow can easily outcompete the likes of Michelle Duggar, and Ms. Duggar is close to the limit for our species.
There are other reasons for hostile action that are likely more plausible, like disliking competition.

referencing various Theosophists' works.About eighteen million years ago, say the strange and ancient legends of our little planet, at a time when Mars, Venus and Earth were in close conjunction, along a magnetic path so formed came a huge, shining, radiant vessel of dazzling power and beauty, bringing to earth ‘thrice thirty-five’ human beings, of perfection beyond our highest ideals; gods rather than men; divine kings of archaic memory, under whose benign world-government a shambling, hermaphrodite monster was evolved into thinking, sexual man.

CS decided on some criteria:
- The account is committed to written record soon after the event
- A major change is effected in the contacted society after the encounter
- No attempt is made by the contacting civilization to disguise its exogenous nature

CS then mentions how in Sumerian mythology, stars are gods that form a seemingly representative and democratic assembly. Sort of like some galactic federation.At Babylon there was (in these times) a great resort of people of various nations, who inhabited Chaldæa, and lived in a lawless manner like the beasts of the field. In the first year there appeared, from that part of the Erythræan sea which borders upon Babylonia, an animal destitute of (or endowed with) reason, by name Oannes, whose whole body (according to the account of Apollodorus) was that of a fish; that under the fish's head he had another head, with feet also below, similar to those of a man, subjoined to the fish's tail. His voice too, and language, was articulate and human; and a representation of him is preserved even to this day.
This Being was accustomed to pass the day among men; but took no food at that season; and he gave them an insight into letters and sciences, and arts of every kind. He taught them to construct cities, to found temples, to compile laws, and explained to them the principles of geometrical knowledge. He made them distinguish the seeds of the earth, and shewed them how to collect the fruits; in short, he instructed them in every thing which could tend to soften manners and humanize their lives. From that time, nothing material has been added by way of improvement to his instructions. And when the sun had set, this Being Oannes, retired again into the sea, and passed the night in the deep; for he was amphibious.
