Earth is made from star dust. After the big bang there were many short lived stars that created the heavier elements and these in turn exploded. The dust of these stars clumped together and all the elements existed from the beginning of the Earth. Much of the earth's rocks are made from iron, silicon, calcium and carbon combined with hydrogen and oxygen. All matter in the world is either an element or a compound of these elements.
Of course there was no wood at the beginning of the earth unless you are thinking about a mythical Eden. Trees only made it onto land about 470 million years ago.

The earth is a product of the debris that was manufactured in the center of a massive star.
The star became a super nova and ejected all the rocky matter That makes up our solar system.
The rocky matter was combined in a hydrogen field that gave us our solar system.

The mass of the Earth is approximately 5.98 Ã10^24 kg It is composed mostly of iron (35.0%), oxygen (28.0%), silicon (17.0%), magnesium (15.7%), nickel (1.5%), calcium (1.4%) and aluminium (1.4%)[12].
The common rocks of the Earth's crust are nearly all oxides; chlorine, sulfur and fluorine are the only important exceptions to this and their total amount in any rock is usually much less than 1%. little more than 47% of the earth's crust consists of oxygen. It occurs principally in combination as oxides, mainly silica, alumina, iron oxides, lime, magnesia, potash and soda. The silica functions principally as an acid, forming silicates, and all the commonest minerals of igneous rocks are formed like this
