MOTHER FLAME, one that is kept alive by the drums of liberation!
In Skypea there's the legendary panel that we linked to the silhouette of Nika and Ussop beating a drum while humans and animals danced around a huge Bonfire.
In the panel to the right, the moon is shared like a 'D'.
Luffy managed to revive himself against Kaido with his heart beat.
In conclusion, the mother flame create by Vegapunk is artificial, the real mother flame is living inside Luffy and was fully revived when the drums of liberation started playing (awakening).
Luffy is able to power up Uranus, possibly Pluton with his heart beat. This is why the ancient weapons couldn't be used until he came back.
