There may be some doubts about the Western world’s 1st millennium chronology, but surely there can be no issues with the rather more recent 2nd millennium?
A few not recorded cultural events over a long time, the odd year here and there, and they could add up to 1 decade or more. What do you do when new folklore evidence suggests you have a King or event that could not have existed, as your history already has dates with a different story or even worse a similar mythology?
Asphyxiation by volcanic gases then instant fossilisation through electromagnetic transmutation processes? Or 2 dinosaurs sleeping peacefully, not noticing a local volcano eruption when most animals seem sensitive to eruptions before they happen? Bodies not damaged and perfectly persevered with not one single sign of a death struggle?
2 of the 4 fundamental forces are suggested to have an infinite range of effect, action at an infinite distance. These are the mysterious Universal Constant forces that are Gravity and the perhaps slightly more understood forces that are electromagnetic in nature. I am a betting man. Sometimes I even like a drunken gamble. There is a difference.
