The evidence: Guide lines but not tram lines.
My responses below take the view that world view synthesis is an epistemically risky business; it is an activity which trades-off evidential rigor against far reaching narratives which attempt to make sense of the big picture - usually some kind of anthropic sense. World views can be as rational as the sparse evidence allows, but they lack epistemic authority and are inherently tentative and exploratory in my opinion. To use a Christian metaphor; they are a kind of pilgrimage.
Disclaimer: I would concede the point that when it comes to world view synthesis with its open ended fields of evidence different people join different dots of evidence with different narratives and therefore epistemic humility is in order. However, I don't accept that this can be true, without gross rational violations taking place, when it comes to basic science such as the spherical Earth, and its position in space and time. In the case of Flat Earthism, Geocentrism and Young Earthism, Moon landing conspiracy theorism etc. a fanciful world view is filtering down to the basic science level and corrupting it.
