“I think that one of the conversations that we had at the end of Prometheus is, Shaw and David have basically locked in on the coordinates of the planet where the Engineers came from. What does that place look like? Ridley called it ‘Paradise’. What happens when they land on that planet? It doesn’t feel like they’ve gotten there yet in Covenant, Covenant felt like it maybe was a detour prior to them arriving at the place of origin so I don’t want to spoil any place that he might still be wanting to go, but the conversations that he and I had about where the story goes next were largely about the place where the Engineers were from and less the events of Covenant.”

I kneew it that Engineers are not the same in Prometheus as they are in Covenant =)
