Is our god a reptile?

I was reading an article about the Sumerian creation story. It states that we were created by aliens, seriously. It literally states that aliens came to earth, and then mixed their DNA with our primitive ancestors, to create a slave race. I looked more into it and found out a whole bunch more interesting things on this subject, but what I kind of got, that I want to be sure of, is that the type of aliens that did this, called the Annunaki (or something like that), were reptilian. Is this true? I don't want opinions on this idea, I don't believe it, but I am thinking of writing something about it and would like to be sure. I have tried to look this up, but have found nothing.
