Then why don't we continue to go?, im sure there is more to explore
More to explore, like what? They found everything they needed to find on the first exhibition. There is no life on the moon and no way to sustain life. We cannot and will not ever live on the moon. And, the cheese is better in Wisconsin.
The main reason for the exploration was to determine if life was possible. It's not. End of story. End of need. There's no reason to spend an excessive amount of money to go again, ever.
It was indeed one small step for man but proved not to be such a giant step for mankind.
