No, it is based on a book, that is an authority, not evidence. Anybody can write anything in a book.
Those become religions since the nature of the universe is, ultimately, unknowable to the human mind.
How do you know what is "unknowable?"
Just out of curiosity, how many of Ayn Rand's works have you read. I've read the Bible countless times, most of the theologians beginning with Augustine, and the early church fathers. I say this only because, to criticize something, I think one is required to know what it really teaches. Some of things you say sound like you really do not understand what Ayn Rand's Objectivism says.

Much of it is eyewitness testimony. To discredit it, you must have some reason. And that reason must be subjective as there is no extant writing to challenge the veracity of the authors.
How do you know what is "unknowable?"
Is the universe finite or infinite?
It is considered infinite because the data suggests so. But if it is, that is unprovable and unknowable. Also, if it is, the finite mind will not be able to grasp it.
Our instruments (eyes, ears, noses, minds) are faulty, therefore the best we have is a faulty understanding of the universe.
I am not critiquing Rand. I am critiquing the article as posted, and some of your own statements as posted.
Shalom.
