its like the united kingdom and great britain are the same.
Errrm actually no they're not lol
Great Britain is:
England
Wales
Scotland
Northern Ireland
United Kingdom is:
All above plus
Southern Ireland
And some other little islands all around
The British Isles is:
An archipelago consisting of Great Britain, Ireland and many smaller surrounding islands
And a little unknown fact:
"Great Britain" is often used to mean the "United Kingdom of Great Britain and Northern Ireland" (UK). However, Great Britain is only the largest island within the United Kingdom, which includes numerous surrounding smaller islands, as well as Northern Ireland in the island of Ireland.
And in case that wasn't enough:
As recently as 9,000 years ago, Great Britain was not an island at all. The end of the last ice age saw the southeastern part of Great Britain still connected by a strip of low marshes to the European mainland in what is now northeastern France.
