Why do some absolute value equations have no solution?

Because both positive and negative values have a positive absolute value.

An absolute value is the distance from 0 on a number line so it must be a positive number, and so  because of that it is impossible to get or equal -1, this equation has no solution.

So confused right here i need it to be more clearer
