A lot of people can see how aliens could exist as god's highest creation was supposed to be man ( in his own image). An alien would throw a
real big wrench in the works for the theologins, The sanctity of human life would be in question, (are we really better than aninmals?). also we wouldn't be # 1 any more and that is much more than some can handle. Look at what happen during martian invasion broadcast in the 30's , People were comminting suicide , and generally freaking out. If and when actual evidence is found or realease to the public it will be much of the same and worse as it will have a better chance to sink in........I think ...... some will denigh to the end , heck there are still people who don't believe that we landed on the moon and that Elvis is still alive . what ever....
It kind of cracks me up, when you start trying to wrap you head around the number of how many stars, planets , and heck even the galaxies there are to think that god would make it only for us sounds kind strange. I mean you would think he would be hanging around (like the street corner) , just to protect his investment and Last time I looked I didn't see him there, well maybe I should check again........
