how did the earth become?not the religious way?

Answer 1

According to the big bang, the universe was created sometime between 10 billion and 20 billion years ago from a cosmic explosion that hurled matter and in all directions


....at least that's the jist it.

Answer 2

Current theory goes something like this:

The big bang involves all the matter in the universe being thrown outward away from the center of the universe. The universe is overwhelmingly made of the simplest element hydrogen. The material in the universe is randomly distributed, not evenly distributed. Where there is a sufficient amount of matter the gravitational attraction makes large objects start forming. When sufficient mass has accumulated the heat and pressure start nuclear fusion - a star is born. The hydrogen fuses to form helium. Later the helium fuses to form carbon. Carbon becomes oxygen which becomes silicon which becomes iron. The star then goes super nova during which the rarer heavier elements are created (e.g. lead, silver, gold, etc.).

The earth is mostly iron plus some nickel, oxygen, hydrogen, silicon, and many rarer elements. The mass that is the earth falls into orbit around the star that is our son. At first it's a big hot ball but gradually cools and forms a solid crust (but retains a liquid center). The heavier elements migrate toward the center, the lighter toward the surface.

Plant life evolves, adds huge quantities of oxygen to the atmosphere. Animal life evolves.

Answer 3

After a few stars died out and supernova'd a great deal of matter settled and collected in a disc that was to become our solar system. Slowly it formed clumps. The forth planet "clump" as well as the other near in planets collected large amounts of heavy elements (created by the supernovae). The earth collected mind boggling amounts of Iron and Uranium, and various other elements. As it cooled and the sun became active, it began to emit carbon dioxide. Eventually the earth cooled to a level that it could have an actual atmosphere (the earths core is hotter than the surface of the sun even now). The hot metals of the earth released gases that eventually combined to form water. Water also may have come from comets in addition to from the hydrogen in the earth.

Answer 4

Even the experts know you can't get something from nothing without a creator. Bottom line
