Multiple scientific studies and astronomical observations indicate that asteroids frequently collide with each other in the asteroid belt, resulting in catastrophic disruptions and the creation of rubble-pile asteroid families.

The analysis

The claim is specific, empirical, and falsifiable. Retrieved papers directly discuss main-belt asteroid collisions, catastrophic disruptions, and the resulting populations of rubble-pile bodies and families. The evidence consistently supports the premise that collisions are common in the asteroid belt over geological timescales.

Numerical simulations suggest asteroids (101955) Bennu and (162173) Ryugu are likely second or later generation rubble piles.
