No, English was not formed the same way as creoles are. A creole is a language that develops from a pidgin. That's a process of increasing complexity. English underwent _simplification_ due to significant contact with non-native speakers. That's the opposite process and gets referred to as "creolisation", which happens to languages all the time. Almost all the Romance languages underwent some degree of amount of it. Some pidgins and jargons might've developed along the way and influenced the change, but the key difference with creolisation is that the modern language didn't primarily develop out of these.
