if those scientists are so SMART why dont they predict where the satellite lands?

It's probably a mistake to answer such a silly question seriously, I'll do it anyways:
A satellite entering the atmosphere uncontrolled will have an undefined orientation when first entering, will be spinning undefined, and minor differences in the point where it starts entering the atmosphere of significant density make huge differences in the reentry trajectory. To actually predict the landing spot accurately, you would need all data about atmospheric pressure, density, composition (humidity), temperatures, wind speed for every single spot along the early phases of the reentry trajectory at the exact time that the satellite passes through the respective spot. You would furthermore need the exact trajectory and orientation and rotation of the satellite before reentry. Given you had all this data available, you could run a simulation. Problem is - all the computing power in the world would not be enough to hold enough data. Just because the simulation inaccuracy in the early stages would effect incredible deviations for the simulation result. Read up on the butterfly effect if you like.
