I will admit it is not the most enlightened view, but the religious community has a variety of opinions on this matter. For example, Pope Francis is a little more open-minded about the issue, and even seeks to add aliens to his flock. A Vatican Radio story noted the Pope would baptize anyone coming to the church, with the Pope noting the Church needs to move "beyond the limits, go ever forward."
In other news, the General Authority of Islamic Affairs & Endowments (GAIAE) in the United Arab Emirates, issued a fatwa warning Muslims against a Mars mission. The fatwa was primarily aimed at the Mars One mission, where individuals are not expected to return from Mars. In this sense, GAIAE is equating the mission to suicide. Luckily, Muslims in general have been more favorable to space exploration, going as far as creating a guidebook for Muslims working on the International Space Station.
