There is an open thread dealing with Christianity and aliens:
Sentient life in the universe. The OP isn't worded the same, but the responses are probably in line with the responses you would get.
I suggest you check out that thread since you aren't really proposing an argument with your thread.
If you had presented an argument of how you feel such a discovery should or could affect the views of the Creationist/Intelligent design community, then participants would have something to debate.
Not inclined to promote due to an open thread with a similar topic.
