Please. I want facts. Stuff that has been proven. Not stuff about how god created to wold and stuff like that. Thankyou.

Planets are formed from the leftovers of the making of a star.
After the star ignites and enters the main sequence, it is surrounded by a vast cloud of dust and gas. The gas is usually hydrogen, the dust can be anything from sand-sized grains to mountain-sized chunks.
The cloud is unstable and tends to coalesce (bunch up) in certain areas. The dust and chunks come together to make planets like Earth, Mars and Venus; the gases come together to make monsters like Jupiter, Saturn and Neptune. The increasing gravity of the new planets helps gather new matter. As they grow, they are a bigger target for comets and meteors, too.
The latest theory of the Earth-Moon system is that it grew till it was a molten ball smaller than Mars, then collided with a similar young planet. Smack. In the resulting cloud, the lighter elements formed the outer layer, then became the Moon, which would explain why the Moon is mostly devoid of heavier elements. The air and water on Earth now would have been delivered by meteors over millions of years following that event.

Most accepted theory is the "Big Bang". Tiny particles of elements (or dust) created the perfect situation where an explosion (the Big Bang) occurred. That sent streams of energy throughout space. As these tiny particles collected energy, they began to move faster and faster, forcing many of them to collide with one another. This collision of particles created larger masses. This would continue for a long time, building larger and larger masses. Eventually, some of these masses got so big, they would exert a gravitational pull on smaller ones. Those large masses would eventually become suns, while the smaller masses orbiting them (due to gravity) became planets.
Moons are smaller masses that are trapped by the planets' gravitation pull.

ejecta from novae that subsequently coalesces. All planets like the earth, mars, venus, etc are basically rocks...heavy elements that can only be constructed in stars and which can only be released to the planet making process by a nova. Planets like Jupiter are...sort of wannabe stars, lots of lighter elements including copious quantities of hydrogen and helium. They could be failed stars (I don't actually know that for a fact - but I'm certain about the smaller planets).

INGREDIENTS:
* 2 cups all-purpose flour, stirred or sifted before measuring
* 2 1/2 teaspoons baking powder
* 1/2 teaspoon salt
* 1 egg, slightly beaten
* 1 1/2 cups milk
* 2 tablespoons melted butter
PREPARATION:
Sift together flour, baking powder, and salt. In a separate bowl, combine egg and milk; add to flour mixture, stirring only until smooth. Blend in melted butter. Cook on a hot, greased griddle, using about 1/4 cup of batter for each.
Cook until brown on one side and around edge; turn and brown the other side. Recipe serves 4.

Planets are made by an explosion that makes a cloud of gas. After hundreds of years planets are made.

i am sure i will get a thumbs down. yet i will answer this queston.
in the beginning God created the heavens and the earth along with all the heavenly bodies. more than belief it's a fact.
