Also why did God make so many fucking planets if this is the only one with any fucking life? waste of time?
I think most folks that consider this question often align with Carl Sagan's classic comment from his book "Contact" in which he considers the following:
“The universe is a pretty big place. If it's just us, seems like an awful waste of space.” As a believer I see the vast expanse of the universe and everything in it quite differently than Mr. Sagan (who was not a believer).
When I see the universe I see the glory of God, but the reality is that the fullness of that glory and power can't be contained within the universe. Still, I think the vastness we see is meant for us so that we may get some understanding (within our finite existence) of how truly incomprehensible God's power, glory and scope truly are.
Within the scope of humanity's artistic renderings we often find photographs or depictions of nature and space in all it's magnificence, but these artistic portrayals are all merely imitations of God's original handiwork. People are fascinated by God's work and spend their lives trying to understand it (whether they acknowledge that notion or not).
I don't see the vastness of the universe and our place within it and see a "waste of space" or a "waste of time". I see an act of love and purpose.
