Usually liquids have lower density than solids, yet ice floats in water. Can you say why?

Ice is lighter than water since a particular mass of ice occupies more space than the same mass of water. In ice, water molecules are closely packed because of the tight bonding between them. This makes ice lighter than water.

Now my Question is:
If the molecules of water are closely packed in ice then why the density of water is higher than ice and how it makes ice lighter than water?
