The evidence for Earth's magnetic pole reversals comes from the Geological record. If you look at the fossil polarity of a section of sea floor taken across and to either side of a mid oceanic ridge, there is a mirror pattern of stripes where the rocks have reversed polar directions.
Similarly the poles of the Sun reverse every 11 years as the sun goes through a maxima and minima.
In our solar system has magnetic pole reversal
The last magnetic pole reversal, when the north and south magnetic poles switched places, occurred about 780,000 years ago. This is based on geological evidence and the study of magnetic patterns in rocks and sediments.
Yes, in the history of Earth, it has happened a handful of times. When it switches we experience what we call a pole reversal. Right now Earth is currently in the process of a pole reversal (the South Pole is moving northwards).
The pole shift hypothesis is the conjecture that the axis of rotation of a planet has undergone relatively rapid shifts in location. For the Earth, such a dynamic change could create calamities such as massive floods and large scale tectonic events.The evidence shows that no rapid shifts in the Earth's pole have occurred during the last 200 million years. The last rapid shift in the poles may have occurred 800 million years ago,
magnetic field flips its polarity, so that the magnetic north and south poles switch places. This process is natural and has happened many times throughout Earth's history. Reverse pole fluctuations have occurred roughly every 200,000 to 300,000 years.

The sun's pole reversal is tied to the sunspot cycle.

Roughly 750,000 years ago.
