Yes there are other planets that might be conducive to carbon based life.
Well, thank you. My first tiny victory.

For petes sake, out of millions of planets the thought [that some might harbor life] is still just unverifiable speculation.
It is speculation, yes, but credible, in the view of many.
In the case of Mars there is undeniable evidence now that water did exist on the planet for perhaps millions of years. So Mars itself once had conditions more conducive to life, though this is not evidence that life once existed on Mars. Methane has been detected on Mars and though it has been suggested that subterranean organisms might be producing it, this not yet proven.
For those of us who don't accept the existence of God, the only reasonable explanation for life's presence on Earth is that it arose by natural means. How, doesn't matter at the moment. Someone will eventually find an answer and I am content to wait. The very presence of life here, however, suggests that it can arise wherever the proper conditions are met. This is why exploring Mars for signs of past life, or even present life, is so exciting. If evidence for it is eventually found on the red planet then it would seem almost certain that life can arise easily.

What I am saying is, even given that, the fact that we have been unable to find such life of any kind is proof it doesn't exist. It will remain a proof unless there is life discovered.
That is not logical. Absence of evidence is not evidence of proof. We have never photographed a ring shaped asteroid either, but is that evidence one doesn't exist?
The truth is on Earth life is ubiquitous. You have no means of demonstrating that life is not ubiquitous elsewhere. One estimate puts the number of planets in our galaxy that have earth-like orbits at 40 billion. That figure appeared in New Scientist a couple of months ago. As someone who is religious I'd be asking myself what purpose all those planets, and the billions of galaxies we now know exist, have; why would God leave all that real-estate empty? Does that really make any sense?
I also have to wonder why so many conservative Christians are so opposed, in general, to life existing elsewhere? I wonder if the problem might not be unhappiness over the loss of centrality in God's creation? If God has created other beings, then mankind is not first in Creation.
If tomorrow beings from another world made contact with us, how would you feel? I think I would be terrified. We'd be at their mercy, but it wouldn't change the way I saw the universe. I wonder if you would suddenly have to reevaluate what you believed?

I am saying it ain't gonna happen. Save this post for later and I will eat my words in public if you prove me wrong. You aren't going to. We will both know eventually, tho I doubt either of us will obtain that knowledge in this lifetime.
Have you heard of the James Webb telescope? It is planned for launch next year. If successfully deployed in deep space, it may be capable of detecting earth-sized planets around nearby stars. It is about five times the size of the Hubble. It is an exciting time in astronomy.
