Planet formation is thought to be a messy process, as lots of growing planets end up in unstable orbits, resulting in large collisions like the one that resulted in the Moon's formation.
All the evidence for these collisions, however, is indirect or the product of modeling. Planetary migrations are too slow for us to track them, and we can't image planets that are close enough to their stars for collisions to be likely.
