The more you keep up with Astronomy, the more aware you are that weekly, more Solar Systems are discovered that could well harbor "Life as We know it." (It's interesting that The Pope's already sorta Welcomed Extraterrestrial Life..to the Christian POV.)

The Mathematical Probability that there ARE other Life-Bearing Planets among the Galaxies gets Better-&-Better, the more we search...with the Improved Telescopes/Probes we can come up-with.

We'll, of course, have to study THEIR Religions..to put OURS into-perspective..when the day comes we CAN communicate with Other Worlds. (&..heh..then the Question arises...are THEY closer to "The Truth"..than We Are.)
