> bacterium, sure... I don't think we'd find that very exciting.
I think that most people, be them scientists, religious leaders, politicians, or even laymen, will have their lives changed forever. For the religious, discovery of extra-terrestrial bacteria will upend most of the interpretations of their holy books. Those books are the foundation of modern Western society (Do not kill, do not steal, do not take another man's wife, etc). By upending the basis of society we have no idea how humanity will end up. Will we throw everything based on the bible away? Reinterpret them? Will the Jews and Muslims reconcile? Will the Christians set out on another crusade? Will that crusade be to the extra-terrestrial bacteria to sterilize them?

The insemination event which led to your birth also happened only once. However, it is does happen often enough in systems that have the right conditions. And there are trillions of available planets, right here in the Milky Way.

Scientists yes, the rest won't care that much. It'll make the news sure but it'll be out of the headlines within a week. Maybe I'm a cynic but I'd put money on that being the case.
Additionally speaking as a religious person, it wouldn't change any of my beliefs. And I'm struggling to see how it would for others of my faith really.
