[MCU] Why did nobody else try to stop Thanos in the universe?

So obviously for the movies sake they focus on the Avengers and Guardians but what about all the other powers in the universe. After half of all life was snapped did nobody else try to find the stones, track down Thanos, or try time travel. There must be millions of civilizations more advanced than anything we've seen where were they during all this?

Most government are reeling from the effects of the snap.  It's implied that maybe bad things are happening because of it.  Piracy and war could be out of control.  Many leaders disappeared, and power struggles probably resulted.  Captain Marvel said "Not everyone has you (the avengers).  Many places are too busy dealing with their own problems to muster the vast strength it would take to challenge Thanos with a full gauntlet.  Earth is uniquely equipped to handle the job with their unusual amount of superheros.
