Pop go the stars
For our universe to produce minds, we require many different chemical elements. Those elements were created by the stars.

Heavier elements, anything heavier than iron, require the stars to go pop—to explode into super novas which create the rest of the heavy elements.
Here’s a page on Nucleosynthesis, the process that created the chemical elements that make up our planet, and us.
