I played on peaceful , on creative mode on flat land with the default first old classical texture pack.

What did I create? I tried building things out of ruins and dirt. I really loved the first time I played the game, because it makes me wanna enjoy the first texture pack even more on flat land.

Flat land is kind of boring , But it's okay when you first start playing mine craft.

I built ruins and facilities out of plain on dirt and made a lake or river and just built the design out of my imagination.
