There might be life out there in the way of germs, but there are no other souls out there. The bible says God shares His business's with us because we are His friends. He commanded us to preach the gospel to every creature. God has never told us to do something that we cannot do. If there were souls to preach to out there, many would have died by now without hearing the gospel.
No, God is in control of all things- if there were aliens He would have had to put them there, and not loved them enough to share the gospel with them. The bible says "For God so loved the world (singular) not worlds (plural). He gave his only begotten Son for this world, do you think He's going to do it again for another world? If they were sinless they'd be in heaven, if they were sinners they'd be on the earth to hear the gospel.
