This has baffled me for years...did he retcon Prometheus?
In Prometheus we see the following evidence there were Aliens that were already created
- When the crew find the dead bodies of piled up engineers, their chests were clearly broken out
- There was some sort of 'shrine' to the alien egg, AND, on the wall you clearly saw the ALIEN set up like Jesus on a crucifix
So if David created the Xenos, what did they find in the Prometheus military out post?
