Origin Poem by Rich Reitz

Whenever I hear of the 'Big Bang Theory'
It makes my eyes grow rather teary.
I think the theory's rather odd;
We came from a bang, and not from God.
But scientists insist we must
Believe the universe came from dust;
Squeezed in a black hole so tight
That nothing escaped, not even light;
Until it went critical and exploded out,
And that's how the universe came about.

Believe in this theory if you must.
But who created that cosmic dust?
