...lost $10 billion,? Bill Gates lost $7 billion and I lost $80,000. Who has got this money? Who made a profit on every ones lost?

The value of the investments declined. If the value of your car goes down, no one has your money. The same thing applies to investments in securities. There is no need to have an equivalent gain for every loss. That said, there are those who short stocks (borrow shares and sell them, buying them back cheaper later to close out their position) and do indeed make money when others lose it.

I took all my money out of the market in August of 2007.
I put it in cd's and bought some treasuries.
Also bought some gold.
Some people paid off their homes and cars.
