Would the existence of aliens disprove religion?

They will try to somehow fit aliens in the Bible if aliens are discovered. I promise you they are not in there at the moment, but they would try to figure out any way that they could maintain their beliefs. According to the Bible Christ was supposed to have died for our (humans) sins. Last time I checked there was only one son of god so therefore I believe if we encounter alien life (which some believe we already have) The Bible, Judaism, and Islam would definitely fall apart.
