Originally from comets that bombarded the Earth in its early formation history.

You could tell her it comes from two hydrogens and an oxygen, which is true. You might try a few of easy science demonstrations you can do at home. Put some water in a pan and boil it on the stove. Explain that the steam is really hot water that turned into water vapor (water in gaseous form). Then watch as the steam condenses back into water in liquid for as it hits a cooler surface. Explain that the steam is like a cloud and the condensation is like when rain comes out of the cloud. Then put some (liquid) water in a ice cube tray and put it in the freezer and explain to her that ice is really just solid water. Then, put some ice in a glass of soda and have her notice how the ice cubes are a lot smaller when she's finished with her pop ... because the ice melted.

The planet was formed millions of years ago from all the elements in the solar system. As it cooled on the surface, the centre was still very hot. Just as a boiling pot will throw off its lid, the heat had to escape through the surface as volcanoes. Lava and gases erupted into the young atmosphere. This contained millions of tons of hydrogen molecules and oxygen molecules that were able to combine in the intense heat and lightning storms into water. The water covered the earth, was evaporated into clouds and dispersed into the ground. The clouds would cool and rain would bring the water back to the ground. The rivers would flow down hill into huge valleys and eventually become the lakes and oceans. The heat of the sun would again evaporate it forming water vapour which in turn becomes clouds.

Daughter wants to know, and Mummy and Daddy don't know. Be honest. Your daughter should then ask where rain comes from. You say clouds. Where do clouds come from?
When mummy washes clothes and hangs them out to dry, all the water from the clothes goes up into the sky and makes clouds. Clouds are little drops of water which feel lonely and join together to have a party. When a lot of drops of water get together they fall out with each other and some of them decide to drop out of the crowd. They come back as rain drops.

The water on earth originally came primarily from volcanoes and comets. Now it is cycled through the oceans into rain and snow, then back through rivers and lakes to the ocean. Along the way, some of it gets sidetracked into pipes to bring water to our homes and other places. After we use it, this water also eventually goes back to the ocean and into the cycle.

Water, in Chemistry, is the equasion H2O, basically the product of a reaction between Hydrogen and Oxygen, and in water to every two particles of Hydrogen there is one of Oxygen, explained here:
H = Hydrogen
2 = Amount of particles in the previously named element
O = Oxygen
Which means there is two particles of hydrogen and one of Oxygen, seeing as for Oxygen there is no number specified.
I'm not sure what the reaction is, I think it's when you burn Hydrogen, but that makes some sort of Hydroxide, I think... Well, some reaction happens. The particles collide, etcetc.
I hope this helps! (Well, it won't, your daughter prolly won't understand half of what I've said, but you know now, eh?)

Show your kid this website.
Its called the "water cycle" and it explains how all water on earth starts in the oceans, evaporates into the atmosphere, comes back to us as rain, is used by animals and plants, and is eventually returned to the ocean.

ice, water really comes from water that evaporates and then rains down again.
