How do we know how earth looked like millions years ago? Like places of continents and how they moved?

We know the direction and speed they are moving now, so we can just run that in reverse to get a good idea of what they looked like in the past.
We can also use fossils and different minerals, where you might find groups of species and mineral that appear in locations on totally separate continents [it’s likely those locations used to actually be next to each other](https://letstalkscience.ca/sites/default/files/styles/x_large/public/2022-11/Fossil_map.png?itok=TIWoaj02)
