Here's why:
* Stars are suns: Our sun is just one star among billions upon billions in our galaxy, the Milky Way.
* Galaxies are vast: And the Milky Way is just one of countless galaxies in the observable universe.
* Stars are born constantly: Stars are constantly forming in nebulae (clouds of gas and dust) throughout the universe.
So, the universe is teeming with stars, and each one of them is a sun in its own right!
