Summary confidence: low
This dataset is a single-row JSON document at phenomena.json containing 7 top-level fields: bigfoot, crashes, earthquakes, ghosts, metadata, meteorites, and ufos. Every column was flagged as 'unknown' kind and 'skipped' during profiling, which strongly suggests each field holds a nested structure (array or object) rather than a scalar — the file is a container of sub-datasets, not a flat table. The first thing to look at is the shape of each nested field individually; treat phenomena.json as an index and profile each key as its own dataset. Start with 'metadata' to understand provenance, then expand the phenomena collections (ufos, bigfoot, ghosts, etc.) one by one.
