There are many features that are explained by a single supercontinent in the mesozoic that no other theory has been able to explain satisfactorily. The jigsaw puzzle arrangement of the continents is not just the shape, layers of rock match up amazingly well on different sides of the oceans. If you have ever studied stratigraphy, you know that is pretty convincing by itself. Then add to that the current speed and direction of the continents today as measured by satellites and other means. Extrapolate those movement backwards, and the continents join together. Even biological evidence like the distribution of oak trees points to Pangaea. The list of things like that is very long and detailed.
It would take a pretty convincing theory to displace Pangaea. What have you got?

Yes i believe it existed because all the continents looks like if they can fit right next to each other.
Also, scientists also believe that in a few million years or what not, all of the continents will slowly come closer and closer together until all the continents/lands are placed together into this huge slab of land. They also said that California will go underwater.... but that is another theory ^_^

well it happens cyclically
about every 500 million yrs the plates reconverge
it has happen a few times already that we know of
and it will happen again
the continents are drifting about the same rate as your finger nail grows

Yes as i remember--it was not very nice place for people to live-and i glad it did exist--continental drift--makes for a nice planet to live on

probably existed. if you look at the coasts of Africa and the Americas they kind of are inverse twins like they used to fit together and this is the same for many other continents.

yes. judging from the evidence presented by Alfred Wegener(pronounced as Vegener; he was german) i find it hard not to.

Why would you not think it existed?
The evidence for it is staggering.
