matthew, I agree with where you arrive, but not how you get there.
I have most definitely questioned the moon landing, even going so far as to doubt it for years, but eventually came full circle and see sufficient evidence we went.
That's neither here nor there, however, as your point still stands: so what?
We belong here, God created Earth and everything in it for us to live here, but I have no problem with him giving us the solar system and galaxy to explore. Unfortunately, the wonder of the cosmost buttresses my faith, but tends to foster unquestioned philosophical naturalism in most, but that is not the fault of space, nor exploration of it, but of man.
I too find the 'obvious' assumption that we will find intelligent life, or that it is necessarily out there to be a distraction and a canard towards philosophical naturalism as well. We've been looking and landing, and now scanning for 'earthlike' planets and finding a 'good candidate' a week it seems, and still no benevolent space brethren to replace Christ as our savior and renew the Earth.
