I've been reading a lot of articles recently that say that the existence of 'alien life', somewhere in the universe, is almost a certain prospect. Makes a bit of sense though, seeing as we cannot be the 'oldest' living thing in the universe.
If this assertion becomes true, the chances that 'aliens' will look like us, or even be as developed as us, if we find them first, could be very close to none.
So then think of the phrase 'made in god's image'. Apparently, we all look like god. Just humans. Not other animals, not trees, not the moon. Just humans.
So by default, if said possible alien life exists, and it doesn't look human, by religious logic they are either godless, or our god never existed in the way we believe.
As an opposite flip, if said supposed 'aliens' have a similar religious viewpoint, and our existence nullifies their religious viewpoints, do we attempt to convince them that their god is false, and ours is real?
What if the 'aliens' race is older than ours? Would their previous religious precedents overrule our own religions by default?
What if an older 'alien race' has no sense of religion, or even sees 'faith' as a mental illness of sorts?
