What were the first two blocks in "Minecraft"?

The first two blocks in Minecraft are Grass and Cobblestone. Grass is the foundational block that covers the surface of the world and is necessary for the growth of trees, flowers, and other vegetation. Cobblestone, on the other hand, is a commonly found stone variant that is primarily obtained by mining regular stone blocks. It is widely used in crafting and building structures, making it an essential material early in the game.
