What to do if I cannot find my emacs init file?

I am trying to add haskell-mode to emacs by following these instructions:

http://doc.gnu-darwin.org/haskell-mode/installation-guide.html

This involves that I add some code to my ~/.emacs init file. However, my issue is that I cannot locate my emacs init file. I tried using find commands to locate it, as so:

find . -name "*emacs*"
find . -name "~/.emacs"

However none of these appear to be very successful, as I get either too many results, or no results.

So, given my situation, since I cannot locate my ~/.emacs init file, does this mean it does not exist? In that case, would it be smart to create one myself using the emacs editor? If so, are there any outstanding things I should know before attempting to create one?

C-x C-f ~/.emacs will take you to it.

See the Emacs manual, nodes Init File and Find Init.
