There is plenty of evidence for a periodic cycle of catastrophic pole shifts – but many people have the wrong ideas about Planet X or Nibiru.
Nibiru is totally misunderstood and is not a rogue planet crossing Earth’s path. If a planet came so close to Earth (close enough to cause devastation) every 3,600 years it would eventually have hit directly by now and destroyed Earth completely.
The Sumerians used the word Nibiru to describe a “crossing point” and intended a warning that when the winter solstice sun, accompanied by Marduk’s planet (Jupiter) are conjunct at the crossing point (of the ecliptic and the Milky Way) that is a time to watch for danger.
This rare alignment next occurs December 28, 2019 – and is part of the reasoning behind “End Times and 2019” – BUT that doesn’t necessarily mean a disaster must happen then – just that the Sumerians thought such an alignment at the crossing point (Nibiru) marked the time of the next cataclysm.

The other crossing is of Sirius over the celestial gnomon as depicted in the Lascaux cave: Pleiades via Taurus via Orion. A little bit more obvious, even if it’s rather slow…
tens of thousands of years slower than noticing precession
Well, it’s like an hour hand on a clock, it doesn’t appear to be moving.
Sirius is moving across the Pleiades/Orion gnomon at the current rate of precession of the equinoxes, i.e. one degree every 72 years (50 arc seconds per annum). It’s currently in line, i.e. pole shift is imminent (relatively speaking).
Of course, the counter-precessionary movement of Sirius is well recognised, but explained as an orbit about an invisible (imaginary) companion called Sirius B. Few people will be alive after the cataclysm to notice that it never gets round to orbiting/oscillating back the other way – at twice the rate of precession.
