Are We The Only Ones In The Universe?

Do you think the earth is the only planet with physical life?
Are we the only intelligent beings in the vast universe?
Some people believe that the universe is too big to have only one planet with life.
Others believe that mankind is the only intelligent life form.
Regardless of your beliefs, nobody can answer these questions accurately.
And therefore, nobody can justifiably say he or she is correct and others are incorrect.

Is it fair to ask the ones who think life exist elsewhere in the universe for proof?
Those who think we are the only ones in the universe cannot prove it either.
Nobody knows whether we are the only ones in the universe or not.
This burning issue has not been proven either way up to now.
Humankind does not have accurate knowledge about everything.
We are inferior beings and it is OK to be embarrassed because of our ignorance.

Should we honestly conclude that unknown things do not exist?
Intelligent people should not be so narrow-minded and shallow.
We should entertain the possibility that extraterrestrial beings are somewhere out there.
And we are not talking about science fiction or impossible things.
It is more reasonable to believe that other life forms exist than to rule out the possibility,
But there is no evidence that knowing these things is vital for human survival.

Religious people say superior beings that are known as spirits exist.
They could be right, but they are unable to prove the assumption.
Why do some people think humans are so special to be the only inhabitants of the universe?
If we view humans as special beings, why do we kill one another every day?
The question still remains, are we the only ones in the universe?
We may never find out the truth about life or maybe someday we will.
