Why is this wrong???

In English it would be "Your book there is on/in the desk."
Estar is used for locations of physical objects.
Tu libro está en la mesa.
Hay (impersonal Haber) denotes existence (there is, there are); not location.
Sentence structure.
Possibilities: Tu libro está en la mesa.........Your book is on the table
Hay un libro tuyo en la mesa...........There is one of your books on the table
Certain words such as "Hay" can only be used with certain structures and other words.
