Whats the difference between :: and . in Ruby apart from namespace

Guys.. This is really puzzling and if you could shed some light, it would be awesome..

See this code from ruby docs

File.open("file.rb") if File::exists?( "file.rb" )

Over here, we use 2 different types of calls.

ClassName<dot_operator>method_name and ClassName<name_space_operator>method_name.

Why dont we use use a dot operator in both cases and why cant I use File.exists?("file_name")
