Some Christians believe our planet is the only one to host intelligent beings. I would how they would react if our space exploration eventually discovers that we are not alone in that respect? What if some of them are more advanced than humans, and have discovered the origin of the universe, and prove it has nothing to do with any god? Of course the aliens might find us first!
I doubt whether one can 'prove' or disprove whether God - or whatever one would call an entity - started -or did not start - creation, floo.
That's a matter of faith.
Strange, though, that many astronouts )and a fe cosmonauts) have experienced a spiritual experience during or after space travel, and many 'lukewarm' believers have had life-changing experiences which has enhanced their faith as a result of their space travel.
I'm not suggesting space travel as a tool for evangelism, but the fact remains that it is a spiritual experience (depending on your definition of 'spiritual')
