The universe contains millions upon millions of galaxies with hundreds of millions of stars in each, equalling virtually countless solar systems. Therefore, it's reasonable to say that the probability of life on another planet is infinitely higher than the probability of the universe being devoid of life aside from our own planet. The lack of evidence supporting extraterrestrial life only means we've not been able to conclusively verify it as of this time.

With a data set of one instance of a life-bearing planet, you can't really speculate on probability. Really the term probability is being misused here. Even in a vast, potentially infinite universe of your description, the strongest statement you can make that isn't conjecture is that extraterrestrial life is possible.

The data set isn't just life being on one planet tho. It's that life is made of the most common things in the universe and survives in a wide range of conditions. Life being possible on other planets is the weakest claim you can make. Life being on other planets is more likely than not (based on our current understanding)

You seem to be ignoring that the "proof" you're Doing for wouldn't suggest life is elsewhere, it would prove life is elsewhere. The data and understanding we have now suggests life is elsewhere, but does not prove it. But unlike TCs trollish claim, no one is claiming it's a fact life exists elsewhere.
