Some of interesting facts about the Eternals check out below
WHY THE ETERNALS DIDN’T INTERFERE ALL THESE YEARS?
Do you know who the “Eternals” are? First, you need to look out at Marvel Comics! Based on comics,- “Celestials” (more likely Gods) came to Earth and left 3 species! Humans, Deviants, and Eternals! Why? Humans were the natural beings of the planet, Deviants were the disaster more likely destroyers and Eternals were the race of immortal beings living on earth secretly. Saviors whose responsibilities were to defend the “Deviants”. The Eternals Job is to save humanity when the deviants become the biggest threat to humanity. The Celestial’s work isn’t finished yet.
So where were they when the avengers needed them most at every time earth was in danger?-
Remember in the endgame, we get to know that the Ancient One was also there when Loki and those aliens were there fighting the avengers! So why didn’t she came and helped the avengers? Probably she was the strongest at that time with the help of mystic art, Loki got no chance to win. Why didn’t she interfered? Because She knew that The avengers were enough to handle that situation! We didn’t make any trendy shitty things that time. why? Why The Ancient One was there in the middle of the fight and do nothing? Just think once, you will get the answer!
Thanos was also a deviant! So why the Eternals didn’t show up this time? wasn’t their job?
There might be 2 answers! One is, The Eternals were broken! Or, spirit removed all of their memories as knowing they were the part of eternal! Sprit was one of the eternal with having the power of removing memories! and exactly why he would do that? Because Eternals wanted to live like humans, to get familiar with the human race! They were there all the time watching them grow and go! They are not here to decide who lives or dies! Just like the ancient one, maybe they know what threat is much bigger than those which can properly handle by Avengers and other mortal heroes!
Because there might be a bigger threat or deviant coming to destroy the cosmos! at the trailer, we get to see them making the Unibind. What is unimind? Unimind is a power that is being created when all the Eternals combine their power to one. Idk why they did, maybe the threat already appeared! and lastly, we see all the Eternals looking at the glowing sky. It could be the appearance of the Celestials! Why would they come to earth? They are here to judge their creations! If the judge that earth isn’t worthy of being like this, they would destroy them. In the guardians of the galaxy movie, the collector also explained this same theory!
