I would argue that man created all contemporary versions of God, if that makes sense. Now, I personally don't believe that God created man, but I do think the idea that man created the current ideas about God can co-exist with the idea that God originally created man. Here's why:
Everything we know about the concept of God, in any religion, comes in book form. This is not to discount people who claim to have witnessed God, or miracles, or who feel God at work in their lives on a daily basis. That's a much more personal viewpoint. What I'm talking about is the construction of God-figures through organized religion. And indeed, no matter the religion, our information comes from a text or set of texts that helps define the nature of God.
Yet who wrote those texts? The Bible is claimed to be the word of God, but He did not set it down in his own hand. No, men wrote it. And edited it. And translated it. And re-translated it. And focused on particular scripture for their causes. For example, walk into a bookstore today, and you'll see several different versions of the Bible. In each one, man has created his own version of God, which may be slightly different than the one presented in the next Bible on the shelf. In fact, there's a group out there right now that aims to completely re-write the Bible, to refocus on Old Testament scripture. It's actually rather disturbing, especially if you do believe in the Bible as the word of God...then these people are simply manipulating it for their own purposes. They're called the Conservative Bible Project, & they advocate such things as "eliminating gender neutral language" and changing all references to "comrade" to "volunteer". They also want to add to the Bible, wherever they feel certain phrases are ill-defined or even left out. So they are absolutely creating their own image of God. Link to their website here:
So, I would argue that as of right now, man is creating God. Even some who claim to be working towards God's purposes are changing, editing, and manipulating the texts of religion for their own gain, to promote the image of God as they see fit. Thus, while God may have made men in his own image, man is now re-creating God in his.
