If I may segway...
My first recommendation when one has a question for God is for the person with the question to ask the Person with the answer.
And back to the topic...
As most of you are aware, I believe that Adam and Eve were a special creation of God - before animals actually existed on the earth. I can, as a "creationist" relate my thoughts on the topic.
I do not think it worrisome that intelligent life may exist elsewhere and if life does exist elsewhere, I would imagine that I would get to see it someday. I am not worried by the possibility of life in a test-tube; He never said he could not teach us how to make living things. I would not be worried if science was able to extend life (it has already on average doubled it).
None of the initial questions seems problematic to me.
I doubt that we will create a universe with the purpose He has.
Best regards,
