I think the star map represents the constellation of Lyre, with the Giants or Engineers pointing at Vega, the cuneiform stele actually shown fine lines conecting the stars
Configuration is similar to Lyra, differences can be explained by stellar drift. Vega or Alpha Lyrae was the pole star 12,000 years ago with a cycle each 26,000 years. Lyre is also known as Vulture cadens (Fallen vulture) by egyptians or Fallen eagle by the greeks.
In Prometheus myth, an Eagle (or a vulture in some variants) descend upon the chained Titan to eat his liver. I think the murals depict where the Eagle (punishment) came from: Vega, or Zeus itself.
In mythology Zeus always came to Earth as an Eagle, Vulture or Swan, represented by the Summer triangle Vega (Vulture cadens), Deneb (Cygnus) and Altair (Aquila), the king of gods came from one these three stars.
After Zeus punished Prometheus, he sent Hermes, whose symbol is a LYRE and the FLUTE, to escort Pandora and the box (an urn containing all the evils) to earth, but the box was sealed on time. Later he sent a deluge but again his plans were foiled by Deucalion, descendant of Prometheus.
In hindu mythology, the equivalent of Zeus is Indra, whose son: Arjuna, was an expert in archery (the bow being the horseshoe shaped vessels) and the flute (again). Arjuna posesses the Pasupata astra, a weapon of god Shiva capable of destroying all animal life and cannot be unleashed against lesser enemies.
The pasupata astra effects are similar if not the same as the Pandora's box (the urns) and the Deluge (and all meat died, all animals and beasts and mankind)
Elizabeth Shaw was wrong, first, she omitted the stellar drift, leading them to another place, not the origin. Second, it wasn't an invitation, was a warning, The gods, or a faction of them, were trying to destroy mankind. I think there's a coincidence they arrived at a place were the Pasupata astra was stored. In the myth, Arjuna never used it in the war, instead he returned it to Shiva and later he and his brothers and wife, walked towards the himalayas, and all died except the eldest, Yudhistir. The moon LV-223 had a huge mountain, several times bigger than the Everest, and at the feet of that mountain there were five engineer temples. I believe these are the five tombs of Arjuna, Bhima, Nakula, Shahadeva and their wife Draupadi, as Holloway said: It's just another tomb, and Shiva's weapon stored there along Arjuna's bow.
