Money is anything that is acceptable as payment for purchases or services randered.
Money is what makes man first and his opinions second, it gain respect for man even if they don't deserve it, it is very important in our lives, without money a lot of people will failed to survive, because without it you can not get anything eatable, drinkable, wearable, or buy something usable.
without the availability of money, our lives will be a waste or worthless because it is involved in any aspect of life. For instance, we need money
To feed,
To be educated,
To maintain our physical health,
To drink, because in some communities water is for sale,
For shelter, and
For transportation. etc
You can see that our lives depends on all this, and we need money to provide them, and if we don't have money to provide all this our lives will be worthless.
