Which one is the truth, sir?
Which period do you mean, son?

In order to understand the universal perspective,
first you have to know more than a version of truth.

A very single fact could emerge into many versions of truth,
depends on the number of eyewitnesses and interpretations.

If you hear news about UFOs and aliens in normal daily life, do not just easily believe in it. But if you hear news about series of natural disasters and serious incidents in the sky, then try not to be terribly shocked when their presences can be detected by human eyes.

There was a skeptical man with a credo, 'Seeing is believing'. One day he found something so alien and said, 'I can't believe what I just saw'. There was other man with different credo, 'Blessed are they who believe without seeing'. One day he found something so alien and said,'This is blasphemy, sinful and evil'.

'Hoax!' The common response for something weird. Then comes curiosity for the people who want to be sure. Then comes long and fierce arguments before reaching the truth.
