The supercontinent that split into today's continents is called Pangaea. It is believed to have been a single landmass around 335 million years ago before breaking apart into the continents we have today.
Most continents fit together the best along their coastlines, such as the east coast of South America aligning with the west coast of Africa. This alignment is evidence of the theory of plate tectonics, where continents were once joined together in a single landmass called Pangaea.
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.
Yes, about 335 million years ago, all the continents were joined together in a single landmass called Pangaea. This supercontinent eventually broke apart and drifted to their present positions through the process of plate tectonics.

Gondwanaland is a landmass thought to have been compromised of present-day southern continents.
Fossils of the reptile Mesosaurus have been found in South America and Africa. It probably couldn't swim between the continents. Scientists theorized that this reptile lived on both continents when they were joined. All continents were once part of a large landmass, called Pangea, that broke apart 250-million years ago.
Several actually but I think the answer you're looking for is Pangaea.

Fossils found on different continents that were once connected can support the hypothesis of continental drift by showing similarities in species distribution and evolution. Fossils of the same species found on separate continents can indicate that those continents were once part of a single landmass. Additionally, the presence of similar geological formations and fossil sequences on different continents can provide further evidence for continental drift.

Pangea
Alfred Wegener's hypothesis proposed that the Earth's continents were once joined together in a single supercontinent called Pangaea. He suggested that the continents subsequently drifted apart over time to their current positions. Wegener's theory of continental drift laid the foundation for the modern theory of plate tectonics.

No, the continents and the oceans have not always been in the positions they are in today. The Earth's tectonic plates slowly move over time through a process called plate tectonics. This movement has resulted in the continents shifting positions and the reshaping of the oceans over millions of years.
