Here is an observation with facts....you can determine how much is just coincidence based on your own logic and reasoning
One side will go Eh, so what that is such a stretch and it was an accident, just a bunch of coincidences...no need for "conspiracy theories"
One side who has researched these people will understand their need for symbolism and why they MIGHT have carried out something so elaborate as part of their rituals ( would not be the first time)
Which side are you on?
