olympus – Did i accidentally rewind my film?

I am a complete newbie to film cameras and I’m experimenting with my dad’s old Olympus Accura zoom xb700.

I put the film in and the S moved and everything, then i took a picture and it showed “1” instead of S and thought great, i did it!
Then, I do not know what the hell I did, I think i fiddled with the rewind button on accident and now the camera won’t turn on and it says “S” again instead of 1.

I opened the back of the camera (which I’ve just learned was a very big mistake) and the film is still laid out, it didn’t go back into the little canister.

Can someone please help me
