Open forum question: Why did god create the world and its people only to destroy it?

Someone called in and asked Mr. Camping a very precise question.
"Mr. Camping, Why did god create the world and its people only to destroy it?"
He referred to the following bible verses and left it at that.
I dont get the reasoning %100 but I believe he means that there are other beings we are not aware of that are observing us as if we were gods project.... go figure.

Paul speaking to the Gentiles:
Ephesians 3:10
8 Unto me, who am less than the least of all saints, is this grace given, that I should preach among the Gentiles the unsearchable riches of Christ;
9 And to make all men see what is the fellowship of the mystery, which from the beginning of the world hath been hid in God, who created all things by Jesus Christ:
10 To the intent that now unto the principalities and powers in heavenly places might be known by the church the manifold wisdom of God,
11 According to the eternal purpose which he purposed in Christ Jesus our Lord:
12 In whom we have boldness and access with confidence by the faith of him.
13 Wherefore I desire that ye faint not at my tribulations for you, which is your glory.
