Here’s why it causes a problem for creedal Christian faiths.

They believe in “original sin.” They believe that Adam’s sin in Eden is inherited by all of his posterity.

Christ’s atonement ransoms the believer from the effects of the Fall of Adam.

If an alien race comes here—it is not descended from Adam. The dilemma? It would not have “original sin.” It would not need Christ to redeem it.

Aliens invalidate Christianity.

Out of the many religions I have studied, only Latter-day Saint theology is cosmic in nature and accounts for life on other planets.
