Humans can be cloned, but only theoretically. This has never been done. Scientists have cloned a sheep and other animals successfully, but it did not work well (the sheep died young) and there were many failed attempts. While humans are more complicated than sheep, they are not much more complicated, therefore, the same problems would be expected in human cloning. The big question mark will be around for a long time because cloning a person is very very morally complicated.
