Earth formed (it wasn't made - it formed) out of the solar nebula of our solar system. The solar nebula was a giant mass of gas and fine particles - these are what create new stars/planets. The gravity from all that material tends to pull the material toward the center of the cloud, and as things are pulled to the center it sets the cloud spinning. The centrifugal force of the spinning flattens the cloud out into a disk - this is why all the planets orbit on a similar plane.
The heaviest material was closest to the sun due to its much higher escape velocity compared to gas - and consequently the inner planets are all composed of mostly heavy materials, and the outer planets are composed of mostly light material.
The earth formed when trillions and trillions of pieces of debris were pulled together due to their gravitational attraction - as the planetoid grew in size its gravitational pull increased as well, which caused it to act like a vacuum sucking up everything that was near to its orbit. Most of the material it grabbed would have been tiny - but some of it was huge. About 4.5 billion years ago the proto-earth collided with a Mars-sized planet (often called Theia) - this collision spread rocky debris into orbit around the earth and at a high enough speed that it is able to stay in orbit around the earth -- this material condensed to form our moon in much the same way that earth formed out of the solar nebula.
I could go on and on, but I'll stop here. For more information try doing a web-search for "earth formation" or something to that effect. Good luck.

One of the properties of matter is that it possesses a gravitational force.
Molecules and atoms are attracted to each other.
The bigger clumps formed stars. The smaller clumps orbited around the stars and eventually formed planets, moons and asteroids.
The simplest one word SCIENTIFIC answer is: GRAVITY!
