Continuity mistake: Sprite projects one of her illusions to bring back to Thena the memories of her identity. When she says the line "The goddess of war", look at the reaction shot on Thena; for a moment her extended fingertips pops in frame, but only a few seconds later in a different shot we see her dematerializing the blade she was clutching. (00:52:30)
Continuity mistake: Angelina Jolie's stance and the position of her hair change between shots when Sprite dissolves the illusion dome that brought her back to normal. (00:52:50)
Continuity mistake: When everyone looks at Thena for biting the food off her fork with psycho stares at the guests, Kingo's hand goes on/off the mug several times. Particularly obvious when Gil obnoxiously says "I gave you the same thing, Sprite." (00:53:20)
Continuity mistake: Lunch at Gil and Thena's. Gilgamesh offers the mead to Kingo, and puts both hands on Patel's shoulders. Change of angle and Gil has just his left hand on him. (00:53:20)
Continuity mistake: During their lunch together, Sprite turns Gilgamesh's clothes into a baby onesie. Look at Sersi's arm; she changes position between cuts more than once. (00:53:55)
Continuity mistake: When Sersi is talking with Dane in the middle of the jungle, you can tell by the position of her fingertips in the reverse shot that she is holding the phone in a different way than the opening view. (01:10:45)
Continuity mistake: At the beginning of the fight in the Amazon, Sprite runs to Karun to protect him like Kingo asked. In the wide shot there's nobody on the porch behind him, but when she calls him 'young man' suddenly there are a couple of people there. (01:13:00)
Continuity mistake: Sersi falls into the pool with the deviant and the pool is extremely deep, but when she turns the deviant into a tree and gets out, the pool seems shallow enough to stand in. (01:18:39)
Continuity mistake: Sersi is staring at the monstrous tree she shaped the Deviant into. Camera to her right; her wet hair is all behind her back. Close-up; hair cascades in front of her right shoulder. (01:19:10)
Continuity mistake: On the Hiroshima site, Ajak approaches Phastus. She puts her hand on his back, but it's on the shoulder in the next shot, and only later she slips it to his back. They change position also when she caresses his cheek and in the faraway shot that concludes the intermission. (01:24:55)
Continuity mistake: Phastos' son screams excited that Ikaris is Superman; Phastos calms him down with his hand, but his son touches him in return on the inside of the elbow. Next shot and Jack's hand is in a different spot. (01:26:20)
Continuity mistake: When for some reason the two Eternals in Phastos' living room feel they have to hide the fact that they're looking at his family life, they sit down in a rush and Ikaris reads some product placement. The objects on the table change position between shots - for instance, look at the Connect Four board. (01:26:55)
Continuity mistake: When Ajak lands on the fresh snow after she was pushed down, the camera is behind Salma Hayek, and we see her move her hand tap the snow a few times leaving some prints. Reverse angle, and there are fingerprints in the snow around the position her hand is in, showing it moved. (01:40:05)
Continuity mistake: When Phastus starts talking to Sersi about the sphere inside of her, his hand position is inconsistent between shots several times until he mentions the Uni-Mind. (01:53:05)
Continuity mistake: Sersi needs to go all the way up the mountain for the Emergence. Phastus tells "We got you. Go", having a hand on her shoulder, gone mid-sentence and the position of Sersi's hair changed entirely as well. (01:59:15)
Continuity mistake: During the awesome fight between Makkari and Ikaris, he manages to get a chokehold on her; Lauren Ridloff's hands keep changing position on Richard Madden's arm. (01:59:25)
Continuity mistake: When Thena stabs the Deviant, he grabs her spear for a moment, then before the cut pulls the arm back. Next shot and he repeats the movement. (02:04:45)
Continuity mistake: When the Deviant has Thena in his grasp, he caresses her. As he says "Remember", her hair is in front of the left shoulder, and it was all the way back behind the shoulder in the previous shot. (02:05:50)
Continuity mistake: On the beach for the ending, Phastus asks Sersi "How, how did you do it?" Her hair is mostly clean off the shoulder, but in the next shot she has a mess of hair all over that shoulder which goes away again when it cuts back to the previous camera angle. (02:14:00)
Continuity mistake: When Dane and Sersi hug towards the end of the movie, depending on the camera angle she has her right arm above his shoulder or not. (02:20:50)
Suggested correction: It never says that the people who live with Druig in the Amazon in the present day are descendants of the people from Tenochtitlan. Nor does it ever say that the forest outside Tenochtitlan is the Amazon. He's probably been moving around for the last five centuries just as the other Eternals have.

Never ever? He literally says "Do you remember this forest? Beautiful. It's the last place we all lived together. I've protected these people for 20 generations." They split after their argument during the sack of the town. If their base of operations exterminating the mutant space dogs in Mexico was in the Amazon forest, their logistic could use some work.

Just because the last time they fought together was in Tenochtitlan doesn't mean that was the last time they lived together. They may have spent some time living peacefully in the Amazon before moving north to do their business in Tenochtitlan. And just because he's protected the people for twenty generations doesn't mean they're descendants of the people from Tenochtitlan. He may have found them later. We don't know every detail of the Eternals' history. You're just making assumptions.
Necrothesp
You are assuming the presence of a third party stranded for 500 years that the movie never showed before, different from the people that he led out of the city and that we have then to postulate he let go, in a location far off from the one of their last encounter. It's an assumption on entirely new details that you had to make up. My only assumption is to think that what is shown in the movie had purpose and fits, and someone just borked a caption.

Who says they're stranded? He just said he had protected them for twenty generations. They'd probably always lived there. You're making the assumption that they must be the same people because nobody said they weren't. But nobody said they were either. Nobody in the film ever made a connection between the people in Tenochtitlan and the people in the Amazon. No mistake has therefore been made in either the dialogue or the captions.
Necrothesp
I noticed the same problem, the scene indicates the location as "Amazon" (it could be any of the Spanish speaking countries that have part of this forest), but then, Druig comes with the affirmation you pointed. It's obviously a geographical inaccuracy.
They don't speak Spanish in the Amazons.
