It accreted from a interstellar molecular cloud about 5 billion years ago - along with the sun. The start of hydrogen fusion within the sun stopped all further accretion from the protoplanetary disc giving, more or less, the solar system we see now.

The Earth was formed 4.6 billion years ago from the same nebula cloud of gas and dust that the Sun and the eight other planets were formed (similar to the one pictured to the left). However, Earth then was very different from Earth now, and it would have been impossible for life to exist on it. In fact, it is only quite recently in the Earth's 4,600,000,000 year long life that life, resembling modern-day life, has been possible, first with the dinosaurs over 200,000,000 years ago and now with humans and other animals. The Earth is still being formed now. It still has a molten centre which causes volcanoes to ocassionally erupt, and plates on the surface are constantly "swimming" meaning that they collide with other plates and cause earthquakes.

Etched within Earth's foundation rocks — the granites — are beautiful microspheres of coloration, halos, produced by the radioactive decay of primordial polonium, which is known to have only a fleeting existence.
The following simple analogy will show how these polonium microspheres — or halos — contradict the evolutionary belief that granites formed as hot magma slowly cooled over millions of years. To the contrary, this analogy demonstrates how these halos provide unambiguous evidence of both an almost instantaneous creation of granites and the young age of the earth.
A speck of polonium in molten rock can be compared to an Alka-Seltzer dropped into a glass of water. The beginning of effervescence is equated to the moment that polonium atoms began to emit radiactive particles. In molten rock the traces of those radioactive particles would disappear as quickly as the Alka-Seltzer bubbles in water. But if the water were instantly frozen, the bubbles would be preserved. Likewise, polonium halos could have formed only if the rapidly "effervescing" specks of polonium had been instantly encased in solid rock.
An exceedingly large number of polonium halos are embedded in granites around the world. Just as frozen Alka-Seltzer bubbles would be clear evidence of the quick-freezing of the water, so are these many polonium halos undeniable evidence that a sea of primordial matter quickly "froze" into solid granite. The occurrence of these polonium halos, then, distinctly implies that our earth was formed in a very short time, in complete harmony with the biblical record of creation.

Er, which planet? In order to use the word 'this', there must be a qualifying noun in a preceding sentence or clause.

There are a few options. I believe it was created by God. Some others may believe it came from the Big Bang. We really have no way of knowing for sure. I guess you will need to ask your creator when you die.

It coalesed from a nebula, about 7 billion years ago as the sun formed.
