The sun came first, followed by the stars, and then the moon.

Here's why:

* The Sun: The sun formed from a giant cloud of gas and dust about 4.6 billion years ago. It's a star, and stars are the building blocks of galaxies.

* The Stars: Stars formed around the same time as the sun, from the same giant cloud of gas and dust.

* The Moon: The moon formed much later, around 4.5 billion years ago, likely from debris left over after a Mars-sized object collided with the early Earth.

So, while the sun and stars were born around the same time, the sun was the first to form. The moon came along much later!
