Versions and cause-and-effect relationships between events sometimes contradict each other so much that one cannot help wondering if we all live in the same reality.

The claim is that Seattle townsfolk organized the terraforming of the entire city area, but somehow I don't really believe such stories given the tools shown and the cyclopean size of the task.

The earth is full of megalithic structures, many of which can hardly be called natural formations, although the official version says they are. Most are mutilated beyond recognition; they clearly look man-made - though sometimes not so much. Did they witness wars, global cataclysms, merging/separating branches, or are they simply quirks of nature?

There was a dramatic drop in the population. It's like everyone got up and went but no one went anywhere. Just disappeared. Everybody got off the ground and just disappeared. Cataclysm. Planned floods. We had to act tough. Wars were initiated by local structures, not from above. And floods were initiated for the purpose of civilizational replacement. Global sweeps of failed experiments.
