Okay, so I read Orlando’s explanation and first off, while some kind of advanced technological race could have existed two billion year ago we guess, if they had spacefaring technology there’s a good chance they would have left evidence, but more importantly, does not track with what evidence of the past we do have. For one thing that mutants from that time should not look as human like as the issue four hints said, second I hope they get brought back with their biology changed otherwise they are going to die to Oxygen which was toxic to life on earth back then and lead to the first mass extinction when oxygen levels rose.
We do have an idea of what existed at the time. Single cells organisms. I don’t know what this Atlantic article they read is talking about but I think it has some really weird and off ideas about how much science does know about the time period.
Never mind just trying to square this with the central premise….one ancient civilization of humanity’s next stage of evolution was already pushing it, now they want one predating multicellular life on earth. Does this actually add anything to the mutant storyline? Are we going to venture into some story where humanity is some evolution of mutantkind’a ancient ancestors who stole the earth from its rightful owners?
