Sourdough bread

Ten days ago, I started with some flour and water and let it air a few hours outside.
During a few days I mixed some more flour and water in and after eight days, air bubbles came in and I smelled a light sour smell. Out of the blue, yeast had grown and I had a sourdough!

Yesterday I kneaded the dough and this morning I baked it in the oven.
I need some more practising. because the dough remained too wet, that's why the loaf is thin.
I have put some dough aside to make another bread in a few days. (motherdough)
