They were spread apart over a period of time when the earth's crust was moving.
Evidence of continental drift includes the matching shapes of continents, similar fossils found on different continents, and geological features that align across separate continents. These clues suggest that the continents were once joined together in a single landmass called Pangea.

Australia is not joined to another continent.
The shape of the continents and the way they could fit together best suggests the formation of supercontinents in the past. Also, the distribution of biodiversity gives us information on which continents were joined and at what point they diverged.
When all the continents were joined together as one supercontinent, it was called Pangaea.
The two continents that are joined together are Asia and Europe.
If specific fossils are found in two separated continents, it means that both continents were once joined.
The supercontinent that all continents were once joined to is called Pangaea. It existed during the late Paleozoic and early Mesozoic eras before breaking apart into the continents we know today.
Wegener believed all continents had once been joined because of the similar shapes of coastlines, matching geological formations across continents, and evidence of past glaciation extending from multiple continents, suggesting they were once connected.
