One of the most confusing aspects of "Alien: Covenant" was David's act of killing the Engineers. This action isn't explained in the film, making it one of the biggest questions about the movie. And what could be better than getting the from the creator of the alien franchise – Ridley Scott himself who talked about this specific topic on a podcast.

In the "Alien: Covenant" prologue, which is not included in the theatrical release, David says that he learned the Engineers ways. One of these ways is that they "wipe the slate clean" when their creations don’t follow the desired path. Because David has a superiority complex and aspires to be a God himsekf, he destroys the engineer planet to imitate the Egnineers but his real motives are more complicated than that

Since the last time I discussed this topic, I have uncovered more information about David and his twisted psychology, so in this video will delve deeply into the resons behind David's decision to anihiate the Engineers. In addition to Ridley Scott— pretty much giving the precise answer to this question, we’ll analyze David extended explanation in the early script and the Ozymadiaz poem he recites while destroying the Engineer colony.

So what are the Engineer ways ? Ridley Scott described the Engineers as the "gardeners of space." They cultivate various life on different planets, including humanity on Earth, the beings on Planet 4, and potentially many others. However, if their creations stray from the intended path that the Engineers have set, they "wipe the slate clean."
