I aree with ebia.  "It's not man's place to question God," is not really a good answer.  I was asked this question, "What is the purpose of God putting us on earth?" by a Mormon.  You can bet he has a good answer (spirit children sent to earth to learn and then go back to heaven to become Gods & Goddesses). I guess the only way to respond would be to put him on the defense and dispute his doctrine, however...I'm not really answering his question to me.  I already answered that we were created by God and are here to glorify God, but I have not answered why God put us on Earth.  I agree with Sower, but I can see this is going to open up a very long discussion on Adam/Eve, the fall, God's Sovereignty, why God puts people on earth and doesn't save everyone, etc.  He already doesn't think the Christian God is "fair."  Apparently they believe that as long as you don't rape or murder, you acheive some sort of place in one their heavenly kingdoms.  Anyway, I was hoping there was something that I had missed.

I know that God created us, but why did he put us on earth?  And if he is all knowing, then why did he allow Adam and Eve to fall?  What is the purpose?
