So wait, Galan, from the previous universe, became one with Eternity of the previous universe during the death/big crunch of that universe, being housed inside of a "cosmic egg". During the Big Bang of the current 616, this Cosmic Egg which Galactus was inside of gestating, is expelled and ends up in a solar system somewhere out there (according to the original story). In original continuity, Galactus emerges from his egg/gestation chamber after millions of years and then sets about creating his Armor and Taa II in the solar system he hatched in. Then later it is added to his story that Galactus was active back before the Elder Gods and other concepts not part of the Cosmic Compass (that being Death, Eternity, Infinity, Oblivion, and I suppose Order and Chaos and Mephisto for some reason) were conceived of and the Proemial Gods (Tenebrous and Co) existed as a kind of cosmic place holder until the rest of the universe took form.
Now, with this new thing with the Asgardians finding and planting a "Galactus Seed", is this the seed/egg that will, upon the death/Big Crunch of the 616, be the vessel for 616 Eternity and whichever being it is from this universe that becomes Galactus in the new universe, or is it something else entirely?
