From the point of view of the Celestials, the removal of half of humanity would not impact their plan to use Earth as a breeding ground for sentient antibodies. After the “snap,” humanity either would have reversed Thanos’ actions and returned to their full numbers or would have eventually repopulated to the point before their halving. It’s also worth noting that if if Thanos was actually right, his actions would have helped ensure the survival of humanity, and the continuation of the Celestials' experiment. Since the Eternals’ role was to prevent the eradication of humanity, and that humanity would continue to exist no matter how Thanos’ machinations played out, it would make sense for the Celestials to conclude intervention from the Eternals wasn’t warranted.

While Eternals Celestia #1 could offer a convenient retcon for the MCU not featuring the Eternals during the events of protect mankind from the Deviants, which would be a major departure from the Eternals lore of Marvel comics. It seems unlikely that the MCU will adapt the plot points regarding the exact horde humanity was meant to oppose, and the accidental creation of humanity from Aaron’s Avengers run, so the events of Eternals Celestia #1 are likely non-canonical to the MCU. It also raises the question of why the Eternals and the Celestials in the Marvel Comics chose not to interfere during the Infinity Gauntlet event by Jim Starlin and George Pérez, considering Thanos’ agenda was to wipe out all life in the cosmos.
