Good Question :k:
If there are subtle hints and pointer available then why not join the dots ( as you said yourself 
)
In old ages magician used to show events of past and far flung places on magic crystal ball. and people believed it was magic.
Now we see the same thing on our tv sets, but we dont consider it magic, because it makes sense to us 
People with limited exposure, knowledge and understanding can still see the television set as magic crystal ball.
