When Man created Evangelion, were we trying to create a clone of God?
Of course. Humans can only exist on this Earth. But the Evangelion will be able to exist forever, along with the human soul that dwells within it. When the Earth, the Moon and the Sun are all gone, EVA will exist, so long as one person remains. It'll be lonely, but as long as one person sill lives...
...it will be eternal proof that Mankind ever existed.
