Asteroids are small free-floating bodies traversing the universe, they can be monolithic, or clusters of smaller rocks and rubble. Most that impact us break up and burn in our atmosphere, becoming smaller meteorites.
Your prompt is ASTEROID.
Monolith of death
Punching craters in the soil
Your reign, extinction

First kiss in moonlight
Will feelings be blown to bits

Nature’s astronaut
Come to Earth for a visit,
You’ll turn into crumbs
