No, Rand literally didn't believe in God. Goodness man, either agree or disagree with Rand's opinions, but at least learn what they are before you do so.
To read Rand and then to think that she didn't believe in God just because she said so, is to not understand why she wrote at all. She stood up to monumental evil solely to try to protect human life from catastrophe. That, to me, is belief in God. That she declared herself atheist merely means she never found a religion that appealed to her.
I recommend Luke 10:25-37 for an example of what Jesus taught about the value of doing over saying in the eyes of God - the difference is nothing less than eternal life.
