In the grand scheme of things, Thanos and the snap was insignificant.
but you can look at it 2 ways. The snap prevented the celestial from being born. Stopping Thanos would’ve sped up the emergence and earth would’ve been destroyed.
But then the movie clearly states, they were instructed not to interfere. Humans were merely there to provide enough energy for a celestial to be born. The Eternals were there to make sure nothing happened to them via deviants.
Bumbass lazy bytchass Celestials. This why I'm a proud Knull fanAjak, the prime Eternal's (angels) directive was to not get involved with human affairs beyond protecting them from Deviants (demons) and ecouraging population growth.
This is akin to the angels in the bible becoming "fallen" for getting to invested in the human experience. They were supposed to babysit humanity til it was time for the emergence/rapture.
