How do you feel the Earth and Solar system were formed? Or how are Solar Systems formed?
Well a lot of people prefer simple explanations like "God did it" and I can understand why, but I prefer the truth(or close enough to it), even though it's confusing.
The Earth formed as part of the birth of the Solar System: what eventually became the solar system initially existed as a large, rotating cloud of dust, rocks, and gas. It was composed of hydrogen and helium produced in the Big Bang, as well as heavier elements ejected by supernovas. Then, as one theory suggests, about 4.6 billion years ago a nearby star was destroyed in a supernova and the explosion sent a shock wave through the solar nebula, causing it to gain angular momentum. As the cloud began to accelerate its rotation, gravity and inertia flattened it into a protoplanetary disk oriented perpendicularly to its axis of rotation. Most of the mass concentrated in the middle and began to heat up, but small perturbations due to collisions and the angular momentum of other large debris created the means by which protoplanets began to form. The infall of material, increase in rotational speed and the crush of gravity created an enormous amount of kinetic heat at the center. Its inability to transfer that energy away through any other process at a rate capable of relieving the build-up resulted in the disk's center heating up. Ultimately, nuclear fusion of hydrogen into helium began, and eventually, after contraction, a T Tauri star, ignited to create the Sun. Meanwhile, as gravity caused matter to condense around the previously perturbed objects outside of the new sun's gravity grasp, dust particles and the rest of the protoplanetary disk began separating into rings. Successively larger fragments collided with one another and became larger objects, ultimately destined to become protoplanets. These included one collection approximately 150 million kilometers from the center: Earth. The solar wind of the newly formed T Tauri star cleared out most of the material in the disk that had not already condensed into larger bodies.
The nebular theory maintains that 4.6 billion years ago, the Solar System formed from the gravitational collapse of a giant molecular cloud. This initial cloud was likely several light-years across and played host to the birth of several stars. Although the process was initially viewed as relatively tranquil, recent studies of ancient meteorites reveal traces of elements only formed in the hearts of very large exploding stars, indicating that the environment in which the Sun formed was within range of a number of nearby supernovas. The shock wave from these supernovas may have triggered the formation of the Sun by creating regions of overdensity in the surrounding nebula, causing them in turn to collapse, and may have altered the composition of the early Solar System
As the nebula collapsed, conservation of angular momentum meant that it spun faster. As the material within the nebula condensed, the atoms within it began to collide with increasing frequency, causing them to release energy as heat. The centre, where most of the mass collected, became increasingly hotter than the surrounding disc. As the competing forces associated with gravity, gas pressure, magnetic fields, and rotation acted on it, the contracting nebula began to flatten into a spinning protoplanetary disk with a diameter of roughly 200 AU and a hot, dense protostar at the center.
After 100 million years, the temperature and pressure at the core of the Sun became so great that its hydrogen began to fuse, creating an internal source of energy which countered the force of gravitational contraction until hydrostatic equilibrium was achieved. At this point the Sun became a fully fledged star
From this cloud and its gas and dust (the "solar nebula"), the various planets are thought to have formed. The currently accepted method by which the planets formed is known as accretion, in which the planets began as dust grains in orbit around the central protostar, which initially formed by direct contact into clumps between one and ten kilometres in diameter, which in turn collided to form larger bodies (planetesimals), of roughly 5 km in size gradually increasing by further collisions by roughly 15 cm per year over the course of the next few million years. And the force of gravity formed them.

I'm trying to figure out whether people on this page are joking or not when they're talking about the Big Bang. I have a sneaking suspicion that they aren't.
None of the explanations regarding the Big Bang on this page are even remotely accurate, but that point is moot, since the Big Bang had about as much to do with the formation of the Earth as the construction of a farm has to do with where eggs come from.
okay well the big bang theory...which basically says that a big comet came and knocked chuncks out of the moon thats why it has all those crators and bumped into planets that were between mars and venus and the heat from the sun molted them together and earth was knocked into gravity behind venus...ands thats basically it
a long long time ago two galaxies got to close and they hit witch we call the big bang. during the big bang mediors were sucked into the milky way and headed strait for the earth when these mediors hit earth they got stuck in the earth now we call those mediors land
I have NO idea, I think earth was formed from a chunk of the sun booming out and then it cooled down except for the middle still ( the core) that would be my scientific guess. either that or god
GOD made the Earth and the solar system and solar systems.:)
how did god create the world when he wants even born then?
It is due to the BIG BANG PHENOMENON.
God made everything!:)
the big bang
