Factual error: Atlantis was in the Sahara when it was still an ocean, that was about 4000-8000 years. But part of the riddle was to find the king, Romulus. Rome was founded around 750 BC. So no way for him to know where they would build a statue about someone that wasn't born yet.
Continuity mistake: When Aquaman picks up the bottle containing a map in the Sahara, he is originally holding the bottle from the bottom while starting to unravel the map. The view cuts unravelling the map from his POV, and he is suddenly holding the bottle from the top. (01:21:29 - 01:23:19)
Other mistake: When Arthur meets Atlanna on the beach, she steps towards him. When the camera zooms out, there are no footprints in the sand.
Other mistake: During the final battle between Aquaman and king Orm, notice the propellers, both left and right prop rotate in the same direction, however the physical lay-out of the propellers are not matching (mirrored), thus one prop would give forward thrust, the other will give rear thrust. Not logical with both rotating in the same direction.
Other mistake: Aquaman and the princess were in Italy, then they are on a boat, but there is no great deep trench in the Mediterranean, and they couldn't have made it to the Atlantic in that fishing boat.
Answer: No, Vulko said they had unlocked the secret of unlimited energy whilst the rest of the world still thought the earth was flat. Atlantis was already old by then, so it's definitely older than 2000 years. Atlan ruled over Atlantis for thousands of years. To say Atlantis is over 10000 years old is probably the most accurate.
