Hot gas in the Universe swirls together sometimes and forms a nebula. A nebula is like a VERY big cloud in space that swirls together over millions of years and cools down a little. The gas swirls and cools together tighter and tighter until the gas starts to form lumps . . BIG lumps . . .HOT lumps . . .big hot lumps that swirled and spun around. Our Sun is one of those lumps. Our Sun is a star. When the Sun was still a spinning lump, parts of it splashed off of it as it spun around. Those small lumps of hot gas were flung into cold space and cooled down and became less hot gas and more like lava. The smaller lumps kept spinning and cooling down until they became planets. The planets float around the Sun, captured in her invisible tentacles of gravity. We call a Sun and her family of planets a "solar system". There are millions and millions and millions of solar systems in the Universe. The hot gas that first made the cloud nebulas started out as energy or light. Tiny bundles of that energy formed and we call those bundles, "photons". Photons come together to form matter, like the atoms of gas. Here is a real picture that we have made of the beginning of the Universe when all that energy first appeared:

The Sun

First chronologically? The sun.
First alphabetically? The Earth.


edit
Some people are arguing that the Sun and Earth formed simultaneously. This is false. After the Sun "formed" from the center concentration of mass of the solar system, there was still a lot of gas and dust spinning around it. Collisions among these particles resulted in bigger and bigger particles. As more collisions occurred, collisions became less frequent, since there were fewer bodies. Eventually, the collisions resulted in the Earth. Then solar winds pushed out smaller particles, leaving the mostly empty space of the solar system today.

The Sun, because earth can not live without the sun, the nearest star from the earth and gives the enough temperature to sustain the life in Earth...

the our solar system was made at the same time. The sun and the earth appeared at the same time. if the sun was made first.. then the gravity of the sun would mean earth wouldn't exist..

here's a question.. was earth and moon made at the same time.. or was the moon come out of the sun ?

According my teacher and some refrence books, the sun comes first. But I'm not sure because I wasn't there when God create sun and earth.
