There are two main evidences for this:
1. The continents fit together like a puzzle
2. There are both extant and extinct animal and plant species present on several continents that are not connected

People come to know about life existing on planet Earth in the past by studying bones and fossils. These are kept in a databse and are studied by scientists.
If you are referring to Pangea, the theorized land mass that all continents were once part of, they know this because of the continents' puzzle like features, because things most likely exploded apart, causing the seemingly random shapes of the shores of the continents.
The name of the supercontinent that scientists believe existed millions of years ago is "Pangaea." This supercontinent is thought to have begun forming about 300 million years ago, eventually bringing together all of Earth's landmasses into a single, immense landmass. Over time, Pangaea started to break apart, leading to the formation of the continents as we know them today. This process of continental drift is a central aspect of the theory of plate tectonics.
scientists know the exact spot where an earthquake begins because they use a ritcher scale
Nope
The Pangea puzzle is the theory of the beginning of the continents. It's how the Earth started out. Well it is the theory of how the continents came to be. The legend has it that way back in time, there weren't any continents. There was just one large landmass. Until it started to spread apart. That is when it was no longer just one piece. But there were 7 different landmasses. Over hundreds of thousands of years, those landmasses spread apart into what we know now as our 7 continents.

Actually, Pangaea was all the continents smashed together. But, the two continents that broke apart after Pangaea was created were named "Gondwanaland" and "Laurasia".
You know, continents are chunks of big landmasses. Therefore it is impossible to form continents in just 5 years.The best evidence is that, "why did the continents are still 7 even I'm now 13 years old?"Let's say that it takes millions to billions to trillions of years to form another continent.

The seven continents are: Africa, Antarctica, Asia, Europe, North America, Australia, and South America.

scientists proof of pangaea is there were fosils of the same animals or dinosaurs in all 7 continents
Dinosaurs are reconstructed from fossils, petrified remains, trace fossils, and comparisons with existing animals.
Pangaea is a super continent made up of all the world's modern-day landmasses joined together. Since plate tectonics are now seen as a true discovery, Pangaea later broke up into Laurasia and Gondwanaland, which eventually broke up into the continents we know today.
