Alien life poses a threat to Christianity

Question: Is alien life a threat to religion?
Position‹3 of 3: Alien life would threaten some but not all religions
Argument1 of 3›: Alien life poses a threat to Christianity

Christianity is seen as the least compatible when it comes to religion and extraterrestrial life. Many Christians believe that life exists on other planets. If Christianity can evolve their ideologies around alien life, then other religions have the potential to evolve.

The argument

If Christianity can adapt to extraterrestrial life, then other religions can as well. Christianity is the most rigid when it comes to the belief in alien life since the idea of life on other planets contradicts Christian beliefs. Yet, a considerable amount of Christians already believe in alien life and still practice their religion daily. Some also claim that furthering scientific discoveries also strengthens personal religious beliefs. Christianity is the most rigid and contradictory of alien life. This rejection is because Christians believe in only one God, and that human beings are made from his image. Christianity also emerged from the original idea that the universe revolves around Earth. But as science progresses, many Christians can alter their beliefs. Today, most Christians are comfortable with the idea that the universe does not revolve around Earth, and that Earth revolves around the sun central to the solar system. Other scientific discoveries, such as the theory of evolution, have also contradicted Christian beliefs. In the Catholic denomination, the Bible states we are all descendants of Adam and Eve, the first man and woman on Earth. Evolution contradicts this belief, with humans being a species that has evolved over a lengthy amount of time. Many Christians are now believers in evolution. If theories such as evolution can alter the Christian belief system, the discovery of alien life should be no different.

Premises

[P1]Christianity is the religion whose core doctrines (one God, humans made in His image, Earth-centered creation) are most rigidly in tension with the existence of alien life. [P2] Christianity has historically adapted to other scientific discoveries that contradicted its doctrines, such as heliocentrism and evolution. [P3] If the most doctrinally rigid religion can adapt to such challenges, then less rigid religions can adapt as well. [C] Therefore, while alien life poses a genuine doctrinal threat to some religions like Christianity, no religion need be permanently undermined by it.

Counter-arguments

The discovery of extraterrestrial life would mean the end to Christianity. Christian ideologies are too strict with the idea of life in other parts of the universe, believing Earth and God's people are central to the universe. The belief is that God created the universe for humans—his people.The discovery of extraterrestrial life would reduce the significance of the human race, especially if the newly discovered life form is proven to be more intelligent.

Rejecting the premises

[Rejecting P1] Christianity is not obviously the most rigid case. Nothing in the creeds states that God created no other beings, theologians have entertained the possibility for centuries, and the doctrines named — one God, humanity made in the divine image — do not on their own exclude life elsewhere. [Rejecting P2] Accommodation to heliocentrism and evolution took centuries, was bitterly contested throughout, and parts of Christianity still reject the second. Precedent for eventual adjustment is not evidence that adjustment is easy or assured. [Rejecting P3] The inference from 'most rigid' to 'therefore all others' assumes a single scale of rigidity. Traditions differ in what would actually be at stake — the uniqueness of the incarnation is a specifically Christian problem, and other religions face different questions that this ranking cannot capture.
