One quick point, the various Adventures series are explicitly said to not take place in Earth-616 by the creators and the handbooks. The connection to Galactus arises from the fact that their unidentified reality, dubbed Earth-TRN566 here, is where a crisis with the M'Kraan Crystal therein caused the eventual collapse of the Sixth Infinty, which led to the birth to the Seventh Cosmos.
