The Christian faith maintains that God is the creator of the universe, of all that is seen and unseen. Yet, within the Christian community there has been some disagreement as to what Christians should believe about aliens and what implications for faith result from either a belief in, or the existence of, alien forms of life. Some Christians have said that a belief in aliens is incompatible with faith because it diminishes the unique role of the human race and of the planet earth in God’s plan of salvation. Other persons have stated that the existence of aliens would prove that Christianity (and for that matter all religion) is just cultural superstition and myth inherent to each race (and perhaps to each planet).
However, many Christians do not see the possibility of alien life as being incompatible with the Christian world view. Why? Because such a discovery would only point to the grandeur of God as creator, and that God’s expansive universe and creative power exist even beyond the fragile boundaries of earth’s atmosphere. These aliens may have already encountered Christ in their own way; perhaps Christ visited their planet and their race just as He did the human race. Alternatively, the discovery of alien life and civilizations could open the door for a whole new mission field for Christians to “boldly go where no one has gone before” to proclaim the Gospel and make disciples.
As to actual belief in aliens, the standard Christian position must be agnostic in the true sense of that word. Conclusive evidence as to the existence of aliens has not yet been presented (at least widely) and conclusive evidence as to the non-existence of aliens is virtually impossible to demonstrate. In fact, Christians might recognize that that there is more evidence for belief in God than there is for alien life at this point in history. For those Christians who believe that other sentient forms of life exist, perhaps a first step for them would be to include alien life in their regular cycle of prayer: praying for the welfare of all races, human and otherwise, and peace here on earth and across the universe. If the Christian who prays this sort of prayer is wrong, God will surely understand and answer the prayer as He sees fit.
