The complete list of all appearances in Marvel Comics can be viewed here: https://comicvine.gamespot.com/set/4005-29092/issues-cover/. As a lot to sift through at comicvine link
(I think it's most telling to see publishing order to know what added in later or retconned but way too much here to re-order by publishing date), I will just remark on few interesting details pertaining to parts of Atlantis Attacks Crossover mentioned above:
Uncanny X-men 13(1989 published as part of Atlantis Attacks crossover): Uatu the watcher recounts different tribes on earth when elder god influence
(Marvel borrowing from Lovecraft) still felt. One tribe being the "Serpent men" that worship elder god Set whom are rejected by the celestials on 1st visit as being worthy to experiment on instead selecting another tribe of ancient man to create the eternals, deviants, and humans with latent gene (mutants) from.
Other Issues of Crossover Seem Add Further Detail: Retcon of this "serpent tribe" as the same ones that appear in the Kull the Conquerer and Conan comics published by Marvel now being given a timeline of being between 1st and 2nd celestial visits (this 2nd celestial visit
pertaining to Lemuria and Atlantis's destruction by the celestials is another retconned in detail as well since their apparent destruction was in comics way before Celestials introduced).
*As a sidenote, the lizardmen from Subterannea
(seems many races deviants come from here) discussed here
http://marvel.wikia.com/wiki/Lizard_Men_(Deviants) seem to not be the same as the serpent people. Go figure.
3) Dragon of the Moon
