Why is it a “belief”? Either there are aliens, or there are not. You try to find out. Until that time, your thoughts are hypotheses, not beliefs.

There may be intelligent creatures in the Universe, or there may not be.
We may be able to find out one day that there are. But it seems impossible for humans on Earth, bound by the confines of time and the immensity of the Universe, to ever prove that there are not.

Why is it a “belief”? Either there are aliens, or there are not.

I'm good with either possibility although there is a severe lack of evidence that there is any other life than what's found on earth.

And I don't find any contradiction with my Christian upbringing.(God didn't reveal the Holy Bible in one revelation so why would He have to reveal all his works and wonders in one big wallop, either.)
