Because the processor socket supported by that motherboard is the LGA 775 and the pentium G4560 is socket LGA 1151
The processor socket (also called a CPU socket) is the connector on the motherboard that houses a CPU and forms the electrical interface and contact with the CPU. Processor sockets use a pin grid array (PGA) where pins on the underside of the processor connect to holes in the processor socket. https://www.webopedia.com/TERM/C/CPU_socket.html

Your motherboard has a CPU Socket 775. The processor you linked will only fit in a motherboard with a CPU Socket 1151. It's like trying to fit a DVI video cable into a VGA port. It simply will not work
Going from memory, the S775 CPUs had the pins. Meaning the socket on your board has no pins, and the CPU you want to use has no pins. Even if you got it to fit in the area and slapped a cooler on it, there are no pins to allow data transfer.

775 was LGA like modern Intel sockets, anything before that like 478 had pins
