13.7 billion, actually.

You may say it was the hand of God, but sience says that it was a linking between atoms that really created the Bang.

Erm, nope, science isn't quite sure what caused it.

The sun is as old as the universe.

No, it's quite a few billion years younger.

Earth was created for 4,6 billion year ago, how I don't know; and I would be glad if someone could tell me. At the start it was only water on earth, all land lay under it. As the lands began to rise, some of the rases that lived in the water started came up from the water and started walking on solid ground.

Right after the big bang everything was incredibly hot quark-gluon plasma, a super-dense, super-hot 'fire', if you will. Over time this cooled into Hydrogen, as it did so certain areas became slightly denser then others (thanks to the random motions of all the particles), the denser areas had more gravity, so they drew even more mass into them. Once enough mass was 'collected' this way these globs of hydrogen underwent fusion reactions (These will occur whenever you have a huge amount of a light element), this reaction would fuse the hydrogen into helium and, in doing so, would release vast amounts of heat. We now have our first stars.
Now, stars can only fuse elements up to Iron, so once they'd fused most of their fuel into iron they expand or explode, when they explode they briefly produce other elements and then scatter them into space. These scattered elements re-formed as planets and meteors. Given enough time they'd collect around stars, crash into each other, and fuse. Giving rise to most of the smaller planets, like the Earth.
The Earth, thanks to fairly simple chemical reactions, was covered in a 'soup' of organic molecules, one day some of these combined in the right way to form a molecule that could make basic copies of itself. From then on evolution took over and steadily improved this molecule until it became every living thing you see around you.

They say the sun has passed half its life. In ca 4 billion years the sun will grow, and then swallow the earth. Of course, there won't be mankind on earth then.
|
About 5 billion, and it might not swallow the Earth, it's more likely to simply fry it.
I also hope that mankind is not there, but that we overcome our current obstacles and are living among the stars.

In 4 billion year there is not sure there is any earth left for the sun to swallow, though... I think mankind will destroy the world when we fall.

I doubt it, it takes a lot of energy to destroy a planet the size of the Earth.
Edit: For everyone who's opposed to the Big Bang, the creation of Earth (as outlined here) and evolution please give me some proof that backs up your claims, I've got plenty that backs up mine.
