The short answer is: English is a Germanic language that was first spoken in early medieval England.
It didn't and it hasn't. English is a very cosmopolitan language, made up from Celtic, Gaelic, Norse, German certainly, French, Latin & so on. But at no time has German changed into Engish. ADDED: English evolved from a West German dialect brought over by German settlers. It is in it's base a Germanic language, and not a Romance (Latin based) language such as Italian, French, or Spanish. It quickly mixed vocabulary from other languages such as those mentioned above. If you can speak modern German however you could very easily read Old English, the grammar structure, pronunciation, and vocabulary are extremely similar. During the Great Vowel Shift, English pronunciation changed and that's why it no longer sounds as similar to German. http://en.wikipedia.org/wiki/History_of_the_English_language
