......that's not what I was saying, I was suggesting a human equivalent to finding a single planet when you've conquered Universes of them including I believe multiple versions of earth via parallel universes (though I'm not sure how much of Darkseid's comic story applies to the movies)
and to make it even more confusing, there's multiple versions of Darkseid too
Also he isn't a walking GPS system, he lost everything (allies included) between when he fought on earth and when he returned.
regardless it's not a plothole
Some might say that the one planet that defeated Darkseid might stay with him for all eternity, or wouldn’t his ship have had some sort of tracking device that could take him back to Earth. Still this explanation from Snyder makes sense. Darkseid loses this most ferocious battle and is mercilessly wounded by old gods like Ares. And if none of Darkseid's allies are alive to help track down the Anti-Life equation once again, it could be a bit of a struggle. As Snyder says, his most pressing issue when he returns to Apokolips is not heading straight back to Earth, but dealing with a power struggle on his own planet. A lot of time had passed and a lot of other planets were conquered before Darkseid is in a “position of power” again.
