If you want to know the Creator, all you have to do is simply ask Him to reveal Himself to you.
Keep in mind that this is done on a spiritual level of course, so don't expect someone to come knocking at your door and introduce Himself as God.
Since this is a spiritual journey to enlightenment, in addition to asking for revelation, you must consciously focus on paying attention to subtle signs that will start to appear. If you are not paying attention to the universe, then you will not notice anything.
The Creator is not an intruder or party-crasher.
You must be a true seeker if you want the Creator to bother with revealing himself to you.
Seek and ye shall find!
