“Is Christianity ready for ET?”

This article will examine the theological implications of the prospect discovery of life outside the Earth, as announced by NASA in the beginning of April 2015. I will begin by analysing the possible implications and meaning for theology if microbial life is discovered, contrary to the popular belief that in terms of the doctrine of creation and for Christian theology nothing would really change. I will argue that this fact will have serious implications for the study of the origin of life, and consequently, to our understanding of God’s role as creator. In a second moment, I will analyse the scenario of intelligent life being discovered and what the effects would be for Christianity if that is confirmed.
