The only purpose of this data type is to represent cases where a value is not expected. So you can’t create a Nothing type value. For example, literal NULL has type of Nullable(Nothing). See more about Nullable. The Nothing type can also used to denote empty arrays:
SELECT toTypeName(array())
┌─toTypeName(array())─┐
│ Array(Nothing)      │
└─────────────────────┘
