More or less... there are some disputes over details but that’s the general thrust of the fall of the creation. The old earth and young earth creation theological camps probably won’t see eye to eye anytime sooner than the return of the Lord, but both perceive a metaphysical shift, rooted in a spiritual shift, that came with men accepting the sin of the rebellious angels.
