Kant and Laplace proposed the nebular hypothesis over two centuries ago. A large amount of evidence now supports this idea.

Detailed explanation-2: -The Development of Nebular Theory Kant argued that gaseous clouds he called nebulae would slowly rotate and collapse under their own gravity, and flatten out into a disc. He argued that these flattened regions eventually formed stars and planets.
