6-7 billion years ago the Sun came out. Then it was a little like the Sun that rises every day on our planet. Scientists have named it Protocolize ("protos" in Greek is "the first"). On Protocolize was strong thermonuclear explosions, which resulted in space appeared gaseous cloud. Been hundreds of billions of years before this cloud began to cool down. With decreasing temperature, it began to appear solid minute particles, which gradually formed around an Ancestral giant disk, consisting of cold flow of solid particles and gases. From the inner part of the disk there was a small, consisting of a dense substance, planets: mercury, Venus, Earth and Mars. From the outer part formed giant planets: Jupiter, Saturn, Uranus, Neptune.

Gas-dust nebula, from which arose the Solar system was formed from the products of combustion of large stars. The terrestrial planets are not from the products of combustion of the Sun. Probably others too.

How long have emerged Solar system?
The Bible. Genesis, Chapter 1, verse 1:
In the beginning God created the heaven and the earth...
NOT properly first find out from where and how then lay out the information on the website all started with gaseous clouds and about 4 billion years ago the sun came my uncle is a scientist so don't argue!!
