Those that created the universe, the unreals of John Shah universe. They were never gone really, just became hybrids with man, using Pandutjis Narus, then Peter weyland introduced them as the Synthetics. We see many versions of them all over the galaxy, even the universe was their creation. But their soul or energy type is that of hell, that’s how Sam s ActiveX was compatible with pure Argent hell energy or pure हाय. All over the time line of the universe in AvP we see that they’re the Engineers parents too. Then they obviously dissappeared into their hell dimension. Hell or Argent is not bound by time or space at all. They’re like magic because they created the universe, but live in another dimension called hell. They never stay for long as unreals soon disappear, and hybrids take over, they’ll be referred to in this blog going forward as myth false notion, Argent Haye unreals or Natives. What Sam gave to the world is what we’ll call ActiveX, this thing is some future tech that Doos can’t have, uses it in his praetor suit only, but can’t have, that’s UAC too.
