How can I breed Aerodactyl to have Earthquake and Stone Edge?

Short answer, you can, but why would you.

In all Gen 4 games, Aerodactyl can learn both Earthquake and Stone Edge via TM. This is the only way to get both moves on Aerodactyl in the first four generations. This means that the father can, (or will if you’re breeding with a Ditto,) pass on Tms or Hms. And thanks to sumwun, we know that prior to Gen 5, Aerodactyl is the singular Pokemon that can pass down Stone Edge and Earthquake via breeding, so, if you teach an Aerodactyl Stone Edge and Earthquake, and then breed it with a Ditto, the child will have those two moves.

Your doing an obvious extra step in the process but ¯_(ツ)_/¯

Prior to Generation VI, if the father knows any moves that are TMs or HMs in that game (and in Crystal, moves that are taught by a Move Tutor) that the baby is also compatible with, it will inherit the move. If a Pokémon species that is gender unknown (such as Magnemite) breeds with Ditto, the resultant baby will inherit any compatible TM or HM moves that the non-Ditto parent knows.

sourceAerodactyl is the only compatible father that can learn both moves, so you need an Aerodactyl that already knows earthquake and stone edge in order to breed another one that also knows earthquake and stone edge.
