Which one of the following essentially summarizes Chalmers's response to Paine's objection that Christianity and belief in extraterrestrials are not compatible?
1) The intelligent inhabitants of each planet have their own Christ that came to them for their salvation.
2) Life is abundant all over the universe but other than Earth, no planet possesses intelligent life and therefore there is no need for a saviour on every planet.
3) Earth was the chosen planet for unfolding the Christian scheme of Salvation.
4) That redemption by Christ on Earth propagates through time and space.
5) Christ travels from one planet to another to redeem the inhabitants of each world.
