The fire department could probably look at it and may be able to tell what the cause of the fire was, whether arson or electrical or something else. I would suggest you ask the experts who can examine the actual physical evidence on the site rather than ask a bunch of strangers on YA who are relying on your description alone. You'd be amazed at what the fire marshal can tell from the site.
Could still be an electrical fire
Spontaneous combustion
Lightening strike.
someone tossed a cigarette butt
Arson
OK, first of all this is not a troll and I would really like some ideas. So just now my garden was on fire (a medium fire), it burned down my shed and everything inside it ( there was valuable and memorable stuff inside the shed ). And next to my shed there's a fence which covers up most of the garden. And so next to my fence there is an alleyway which people could just walk freely along (Next to the alleyway is my neighbours house). So I just need suggestions of how it started because nothing was plugged in inside of it (I don't think so...) and it could be that a person through a smoke cigarette to the shed and..????????! Please I'd really like some suggestions of how it started please. Thank-you.
