Well, that depends on what you believe.
In his new book "Religions and Extraterrestrial Life" (Springer 2014), David Weintraub, an astronomer at Vanderbilt University, takes a close look at how different faiths would handle the revelation that we're not alone. Some of his findings might surprise you.
Public polls have shown that a large share of the population believes aliens are out there. In one survey released last year by the company Survata, 37 percent of the 5,886 Americans who were polled said they believed in the existence of extraterrestrial life, while 21 percent said they didn't believe and 42 percent were unsure. Responses varied by religion: 55 percent of atheists said they believed in extraterrestrials, as did 44 percent of Muslims, 37 percent of Jews, 36 percent of Hindus and 32 percent of Christians.
