SQL Server 2014 :: Find String With Spaces And Replace Them With Other String

I have following query which return me SP/Views and Functions script using:

select DEFINITION FROM .SYS.SQL_MODULESNow, the result looks like
Create proc
create procedure
create proc
create view
create function

I need its result as:

Alter Procedure
Alter Procedure
Alter Procedure
Alter View
Alter Function

I used following

select replace(replace(replace(DEFINITION,'CREATE PROCEDURE','Alter Procedure'), 'create proc','Alter Procedure'),'create view','Alter View') FROM .SYS.SQL_MODULESto but it is checking fixed space like create<space>proc, how can i check if there are two or more spaces in between create view or create proc or create function, it should replace as i want?
