You and Saarbebas are going to be a challenge! Youre going to have to explain what you mean by chonologically 7 but for all purposes 17. You need an animal I don't know that your robots will work but when we get that far we'll see. I'm not sure i like the idea of unknowing followers or how it would affect her powers.

Well, she is seven years old. HOWEVER! She has the intelligence and body of a seventeen year old. She's much younger than she looks, pretty much. You know, for people who want to ask how old she is and gets freaked out when she says she's only seven. 

I don't really know what animals would really fit for a machine god so the next best thing I could think of was robots. If it matters, she prefers humanoid robots, like mechs and stuff like that.

I could always remove the whole Atheist part. Lots of people worship machines and technology, and even more people use it religiously (Like us!). A certain caveat with Machina however is that her creators wanted to create a god using mortal methods that did not need "Faith" to sustain it. A sort of "Alternative" power source for them. Machina doesn't get stronger with more people believing in her, she gets stronger as mortals become more technologically advanced, since that's her sphere of influence. Unless the world gets bombed back to the stone age, Machina should grow more powerful with age.
