ELI5: Why does the UK have so many accents despite being a relatively small island country?

Cockney, Geordie, Welsh, Scottish (Glaswegian/Edinburgh), Irish (Northern), Brummy and many more. I know other countries have a large degree of dialect diversity but these countries (such as the US) are massive compared to the UK. So why does this small country have so many accents? Accents that can sound totally different?

Those accents came about from hundreds of years of small isolated communities. People were born, lived and died in the same village without travelling more than 10 miles. So lots of local words and different pronunciations began to develop.
