If you want it simple, say it was the big bang.
But the simple fact is that we don't know what matter is much less what caused it.
It SEEMS to be a form of "frozen" energy (see string theory for a confusing time) and good old e=mc2 goes along with that ... but then you have the question of what causes energy.
The primary causes of soil formation are weathering of rocks, organic matter decomposition, and biological activity. Weathering breaks down rocks into smaller particles, while organic matter decomposition adds nutrients to the soil. Biological activity such as plant roots and soil organisms further contribute to soil formation.
The presence of organic matter in the soil, such as decomposing plant material, can cause it to appear dark brown or black. This organic matter contributes nutrients and improves the soil's ability to hold moisture and support plant growth.
The name given to the attractive force experienced by all matter is gravity. Gravity is caused by the core of the earth and keeps everything from floating away.
When light interacts with matter, it can transfer energy to the matter through processes like absorption, scattering, or reflection. This interaction can cause the light to change direction, slow down (in a medium), or even transfer its energy to the matter, influencing its motion or electronic state.
Factors like rainfall, type of soil, presence of organic matter, and the application of fertilizers can influence the pH of soil. Rainfall can leach minerals and alter the pH, organic matter can buffer pH changes, and fertilizers can either increase or decrease pH depending on their composition.
Cold causes matter to contract. Heat causes matter to expand.
Matter causes gravity in the first place.

Temperature.
Heat causes matter to become warmer, usually to expand,and occasionally to change its physical state.
Gravity is the force that causes all matter to be attracted together. It is a fundamental force that causes objects with mass to exert an attractive force on each other.
Sewage is waste matter from domestic and industrial establishments, what causes it....Humans
No, it's the other way round. Matter is what CAUSES gravity.
Temperature. Temperature causes matter to change state.
