The first answer to "why" is "because I'm using a events driven solution", in other cases I doubt that are used properly. The main benefit I found in messages sent on queues is that your application become independent from the result or consequences of those messages.

it also makes it easier to scale up since the producers are decoupled from consumers

Example Amazon

if the producers (think of an e-shop frontend) put too many messages on the queue you can just ramp-up the consumers (order processing) and clear up the backlog

The term message queue is very general. They are used for many things. Is there a particular use that you are asking about?

The main reason to use a queue is to keep things in the same sequence. So that the first item is processed first and the last item is processed last. Another reason is to have a list of itmes to process when resources are limited. If there is more work to do than the system can do then it must keep a list of what to do when it has completed previous tasks.

When you get in line to buy something then you are in a queue. When there is a line then that means there are more people wanting to make purchases than cashiers that can do the sale. So people queue up (get in line) for a cashier or whatever.
