I assume most are familiar with the fact that a primitive tribe called the "Dogon" met with an anthropologist and claimed to have come from Sirius and stated (in scientific translation) that it was a binary star system decades before astronomers had the technology to find out that it is one.

Crazy, right!?

Except, have you ever gone outside and looked at Sirius? It is the brightest star. When it is low on the horizon, it pulsates colors like a flashing light: red, green, white, blue, etc. it also often looks like a double star.

In other words, it is the most flashy and noticeable star there is, if you were a primitive and decided to claim a star as your home, guess which one you would likely pick? The coolest looking one.

And, even though it is an optical illusion, that star looks like a double star when it is flashing.

It was probably pure coincidence that it actually is a binary star.

Point being, real-life observation is of utmost importance to understand things. Without bothering to look, shit you read might sound convincing.
