Avery Moore
Troubadour
Haven't read all the replies, so sorry if I'm repeating some of what other people have said.
It's fine whether people start with a Prologue or with Chapter 1, I have no preference. The main thing about prologues though is that they should somehow be separate from the rest of the story in some way. There needs to be something about your prologue that makes it different from the rest of the story. Say, for example, if they're set in a different time from rest of the story, or they're told from a view point of a different character, or the main story's written in first person while the prologue is written in third person.
The main point is, if Chapter 1 is just a continuation of the Prologue, then just make your Prologue your Chapter 1 instead.
