Millions of years?

How can you state it as fact that it was 'millions' of years for some of these changes to take place?

There is a tremendous amount

There is a tremendous amount of scientific evidence, especially in the science of tectonics. We can measure the speed and direction that the crustal plates are moving today, and see the evidence of their past movements.


How did Pangea get separated?

The crust of the Earth is

The crust of the Earth is broken into large plates. These plates are still moving today. For example, the United States is moving west at about the same rate that your fingernails grow. As these plates move, they sometimes bring continents together, and sometimes move them apart.
