There are evidence that human can be clone. If it is possible with animals, it can be possible with humans also. The plan of God for us is produce the normal way. Cloning is not a good idea because if God wants us to be clones tell us that. God created everything perfectly without any error. God's ways of doing things is the best not the ways of men. God the only engineer that can do things perfectly.
Genesis 1:31 And God saw every thing that he had made, and, behold, it was very good. And the evening and the morning were the sixth day.
