That's cool, because religion is a VERY personal thing. The only soul you are responsible for saving is your own.
Which of the 800 branches of Christianity do you belong to? Apparently not one that insists that we are alone in the universe.
I'm a Baptist. But a non-denominational Pastor was
instrumental in my being born-again. The path that led me to that was quite long, but to make the story short, I "accidentally" stumbled on this pastor on tv, at a time when I can no longer ignore, and was trying desperately to fill a void - or a "hunger" deep inside. I asked to belong to that congregation to be baptized (I wanted to be baptized), and was going to follow the ministry on tv.....but he advised me to find a church near me that I can worship with them.
I find that the Baptist (in my area) tries to adhere to the New Testament as possible.
Numbers of denominations isn't surprising at all - they could number for millions for all I care, doesn't make any difference - that's been repeatedly stated in the Bible:
wolves in sheep's clothings. false teachings.
Now I don't want to get into about which translation is correct - there are separate threads for that.
Christians are not here to save the world - not in the sense that we try to convert people to our belief. That's a common misconception so many have about Christians. Our commission is simply to spread the Gospel or the Good News. We're not even supposed to force anyone to listen.
I don't think it explicitly confirms anywhere in the Bible that we are alone in the universe.
That being said, I won't be surprised either to find out that we are.
Mankind exploration and understanding of the heavens though, is part of the heritage given to mankind, imho.
God made mankind ruler of the earth,
Genesis 28
And God blessed them, and God said unto them, Be fruitful, and multiply, and replenish the earth, and subdue it: and have dominion over the fish of the sea, and over the fowl of the air, and over every living thing that moveth upon the earth.
and the Scriptures also suggests that even the heavens are subject to mankind.
Psalm 8
3
When I consider your heavens,
the work of your fingers,
the moon and the stars,
which you have set in place,
4
what is mankind that you are mindful of them,
human beings that you care for them?[c]
5
You have made them a little lower than the angels[e]
and crowned them with glory and honor.
6
You made them rulers over the works of your hands;
you put everything under their feet:
----------------------------
Imho, science was created for the sole purpose of glorification of God
(and the heavens provide that), and to fulfill His will.
What we do know from reading the Bible is that the fate of the universe is forever linked to God's timetable for mankind on earth.
