Of course, fans will remember the rising specs of dirt above his coffin which signified all is not lost.

Until now, it was thought that the first reference to Aquaman on screen happened in Batman V Superman.
Bruce Wayne was seen looking at fimed footage of the Atlantean swimming into view before swiftly destroying the offending camera.
Jason Momoa just revealed that Snyder told him Aquaman already played a crucial role in Man of Steel. It's not hard to figure out where, since there is only one particularly epic and memorble scene involving the ocean.
Justice League Superman and Aquaman theory confirmed
Momoa said: "In Man of Steel, when Henry [Cavill] is saving the oil rig and he's holding that up, and all of a sudden he kind of floats up on the ocean, he's [Zack] like 'I had Aquaman save him so that they did cross paths at one point.'
"So then when Bruce goes 'You ever heard of…Superman?' I have met him and we have crossed paths."
Jason Momoa also revealed the most embarrassing moment of his career happened while filming Aquaman in the freezing waters of Iceland.

Justice League: Superman was drowning
Despite all his Kryptonian powers, it seems Superman definitely can't breathe unedr water.
It seems that almost invincible man really could have drowned if the aquatic superhero hadn't swung into action and swum to his rescue. Perhaps Lex Luthor should invest in a big tank next time, rather than faffing around with Kryptonite?
As it is, fans will still have to wait a few more days to see if the Caped Crusader will be resurrected in Justice League.
