yes, all land all once was connected. If you look closely on the map you can see as if all of the continents fit together as puzzle pieces.
There are 50 states in the United States, all of which are connected either by land or water. The contiguous 48 states are connected by land, while Alaska and Hawaii are connected to the rest of the country by water.
The land bridge is now under the Beiring Strait. It separates Alaska from Russia. Early people came to America by that land bridge.
A strip of land connected by two continents is called an isthmus.
North America and South America are connected by a land bridge known as the Isthmus of Panama.
All continents are connected by land masses, although some are separated by oceans. For example, North and South America are connected by the Isthmus of Panama, Europe and Asia are connected by the Eurasian landmass, and Africa is connected to Asia by the Sinai Peninsula.
Pangea was a hypothetical land area believed to have once connected nearly all of the earth's landmasses together.
The theory that all land masses were once connected at a point called "Pangaea" is known as the theory of continental drift. This theory suggests that continents have moved over geological time due to plate tectonics.
Connected
Tasmania and Australia were once connected by a land bridge when the oceans were lower

Since you see the same fossils from on continent to another, it proves that all the continents were once connected. Let's say one fossil of a small animal is found on one continent, and on another far away, such as Antarctica and Africa. It would be impossible for the small animal to swim from Antarctica to Africa or Africa to Antarctica because it is a small animal, after all. Plus, it might not be a sea animal (let's say it's not for this scenario, so that we can prove that all the continents were once connected). Therefore, you can say that they were all once connected since the fossils of this small land animal were found in Antarctica and Africa, and it would have been impossible for it to get across if the continents weren't connected. So, since the continents were connected before, this small land animal could easily walk over from Antarctica to Africa or Africa to Antarctica. This just supports the idea that all the continents were once connected. There are more facts to go into it, such as how all the continents somewhat fit together like a puzzle. Hope I helped :)
Beringia
It is another example that helps scientists with their theory that all of Earth's landmasses (land) were/was once connected. WOOOOOOOOOT WOOOOOOOOOOT
