I think this is a question for the stars themselves, because it's not something that humanity can answer yet, at least not when we haven't been able to definitively prove that there's life on other planets. The universe is far too vast a place for the earth to be the only planet that supports life and that's a fact.
It's thought to believe that all the stars are meant to do is light up the night sky for us and I truly believe that the universe wasn't made randomly, it was created by intelligent design and as such, large balls of fire in space wouldn't have been created to serve as light bulbs.
The rest of the universe is for the other lifeforms that exist on other planets and other galaxies. I bet there's a lifeform somewhere else that's contemplating the answer to this very question that you asked and they'll probably become to the conclusion that there's life out there other than them and the rest of the universe was made for them.
I don't think it will be long before we find life on other planets, and not just any life, intelligent life. The universe was made for far more than just a few billion earthlings, we're probably one of many lifeforms that exist in our universe and maybe one day we'll get to meet these other lifeforms.
I hope this helps.
First we must take into account that "the earth" was not designed for "humans". This has undergone contrasting changes since its inception (for millions of years) and throughout that time lived many very varied species and especially other than humans (who have suffered extinction thanks to these changes). Therefore, humans can become extinct if the earth undergoes a catastrophic change.
Now understanding that (that humans are here at random), the rest of the universe was only created by chance of the interactions between mass and energy, therefore, it was not created for other organisms; rather, "other organisms are generated according to the environmental conditions of other systems in the universe"!
Do you believe in extraterrestrial?
The universe is not designed for one or several entities; the entities or organisms are "designed" according to the variation in the universe. Each one takes advantage of the universe in its own way and at its scale.
It should be noted that, without a universe, there is no existence of entities, so you can not "make" a universe "for" something that does not yet "exist" without it.
there are many planets similar to the earth, that is, there could also be life there, surely not equal to ours. Now, there are many systems in many galaxies where there could be life in different ways.
At this point, we can only answer this question based on theories and imagination.
Even though the scientists already explored quite a distance beyond our solar system and much of what we call observable universe, we still know a tiny fraction of the extent of it.
Microscopic space organisms had been discovered in the past and we've been learning more about the atmosphere of the nearby planets. And although we can "roughly' tell whether the planet is habitable or not, there were no extensive understanding about its true nature and probabibly the organisms that might have or still living in those kinds of planets.
What I can say us that, there are still billions of unexplored systems and several more planets that could be habitable by our kind.
To claim that be are the only species that exist is an UNDERSTATEMENT! Whether proven or not, I would like to believe that there are intelligent species out there that are asking the same question as we are.
Excellent question. This might surprise you, but the entire universe was MADE FOR MAN. Don't be alarmed, I know you would ask how on earth we are supposed to enjoy the entire universe since its hostile to man in its current state?
The answer lies in the revelation from The Bible. We are told that, For the creation was subjected to futility, not willingly, but because of him who subjected it, in hope . Futility means pointlessness or uselessness which explains why we're yet to find any planet that can sustain human life. God has left the universe at it is after the rebellion of Satan. He renewed the earth in Genesis 1 specifically for man to be able to survive. He's calling all to repentance so that they can inherit it all.
The Bible also tells us that For all creation is waiting eagerly for that future day when God will reveal who his children really are . Nothing is there for no reason in the universe, the life we live today isn't for nothing. God is waiting to see those who will be faithful to him in the presence of Satan's influence.
We are also told that God determines the number of the stars and calls them each by name. Incredible!. We are also told that Eye has not seen, nor ear heard, nor have entered into the heart of man, the things which God has prepared for those who love Him.
The Universe was made for man, those that show themselves faithful and are His children.
Thanks and have a nice day.
It's made for no one and free to use by anyone. To claim it is made for man alone is absurd. Given that we are only a speck in the entire universe, it is not mathematically impossible that there are other civilizations out there that have surpassed us.
