I misread this "most likely alive" as meaning "alive for sure". Sorry about the misunderstanding.

The children theory could work out well. A child might feel and look similar enough for Sting and Rogue to mistake it as their parent at a distance. Though with the Humans being accepted as full adoptive children, it would need some explaining why the Dragons never mentioned their real children or unhatched eggs to their adoptive sons. But then so does them actually being alive.
