How can we not say there is life on other planets in other galaxies?

[Agent Fox]

I just saw an inspiring video on youtube you might have seen already. This video reminds us how our universe is too big for our brains to even map out. There are so many galaxies out there, how can we be the only life out there? Our hubble telescope has taken pictures of billions of galaxies that appear as dots the smaller they are, the further. The possibility of life is greater than we can imagine. I know god did not bring humans into this universe as the only life form.

God fits into the equation as the creator of humans. What my argument is why would god only create humans in this huge universe.
Of course we dont know faesson who says we do know. My point is that we must consider how the high the chances are that there must be life out there. We will not know unless we have the technology to travel there.
Some of you are missing the point. Of course we dont have evidence. The fact the the chances of life are high is necessary to consider if we do want to find evidence of life.
