google is not a being, not "she" because its "it", its a virtual tool. "asking" a tool to do something makes as much sense as asking my keys to open a door.
its also not infinite, it was created by humans and its limited by finiteness of hardware and by human will (in case someone decides to delete the program).
google also doesnt know anything as much as a dvd disc doesnt know anything about information stored on it.

edit: its also not omnipresent, but located in certain hardware facilities, we can only access and use it through internet connection.
