You missed my point pad .
This planet is unique because it is OUR place of Human existence .

I missed nothing my friend.
Like I said, unless it is shown conclusively that this planet is the only one with advanced beings [relatively speaking] then we are just one more planet among the many billions that probably exist.
Humanity may just be one of many results of 13.83 billion years of evolution.
If we went back to the origin of life on Earth and replayed the whole history of evolution over again, we almost certainly wouldn't end up with human beings like ourselves a second time. I don't think that most people realize quite how contingent the history of evolution has been. Imagined abstractly, life expands like a tree outward into an unbounded and almost infinite possibility-space, where every point, the tip of every branch, is a different result, a different kind of organism, a different manner of life. The precise shape of the tree is the result of all kinds of conditions, environmental, ecological, competition between different species, the developments of diseases and disease resistance and countless other variables.
Run evolution a second time, and we almost certainly would end up with a different evolutionary tree. We might end up with different kinds of cells, with different chemical pathways, membranes, genetic code and so on. If whatever killed off the dinosaurs didn't happen, mammals might not have enjoyed their subsequent success. The dominant form of dry land animal life might not even be tetrapod chordates if things with different body plans emerged from the oceans long ago and established themselves on land.
And that's right here on Earth. Imagine another planet where conditions are significantly different.
SO WHAT !!!
Humanity ; it's existence is what makes this planet unique.
There's unlikely to be anything quite like it or us anywhere else in the universe.
Who ever said humanity was anything special?
Human beings understand each other. We can talk to each other. We have an applicable innate 'theory of mind' and can attribute thoughts, intentions and emotions to others of our kind. We love each other. There are things we share, like a sense of beauty. That's all stuff that emerges from our evolutionary history, it's things that our ancestors evolved to do in their social groups.
If we ever encounter space-aliens, it's unlikely that we will be able to communicate. Maybe simple mathematics, but not much beyond that. Their innate communicative instincts will have taken very different form than ours. We probably won't have much of a clue what they are thinking. Imagine a nest of intelligent social insects bustling around like ants. Are the insects distinct psychological individuals or do they function more like a group mind? What if they communicate chemically, with very subtle pheremones that they detect with their antennae? What if they/it thinks and conceptualizes abstract ideas in terms of smells? We might be able to form hypotheses about what their intentions were from looking at the results of their labors, but probably not by talking to them.
How do you know?
This is similar to the Ptolemy belief of an earth centered universe.
Billions of planets out there, maybe trillions, and you suggest humanity is unique? Or that Earth is unique because it has humanity?
I don't think that anyone has to deny the possibility of space-aliens to say that human beings are probably unique. Each species of space aliens will be unique too. Just... different.
