Why is a IP address needed?

Our MAC address is unique so we can send packets or frams using MAC address. Then what is the importance of IP address? I think IP address can help to identify location but MAC address help to identify the network. If the same IP address is in the same network, how can we identify the location?

    Assuming this query is originated from an interview question. However, in very brief, ip address/ network address uses for transfering informatiom from one network to another. To recognize easily ip addresses are an easy way, just like your home address. While mac address/ physical address is actually uses for distrubution of information. And it is bit difficult to remember. Also you can follow other good references.
