Our reaction to aliens depends very heavily on what the aliens tell us about themselves. They may be God fearing but without a savior but they may have been told somehow years ago about our Savior and have been looking forward to meeting us for ages.
No matter what there will be a lot of mistrust toward them. At 91 I am going to stay right here on Earth. I’m too scraggly to eat anyways.
God Bless Sir, Merry Christmas.
