Have never understood why anyone would think the existence of life beyond this infinitesimally small speck in the vastness of space would do anything but magnify the grandeur of God. It would mean the spirit that animates living things is universal, in a literal sense.
Take the giraffe. It has a long neck but also has an incredible vascular system that was specially designed to compensate for the fact that blood has to make it all the way up its neck defying gravity. Something only a designer would be able to figure out and construct.
