My current view on the likelihood of life in the universe is based on looking at what we know about the universe. If the laws of physics are consistent, which they are as far as we can tell, then the basics of elements and their interactions (chemistry) are consistent as well. Being that there are a massive number of repeating, and predictable, processes based on these fundamental processes of physics and chemistry, if life arose here from these processes, it doesn't seem unlikely that these same processes would result in life forming elsewhere, especially considering the unfathomable number of instances of likely similar environments throughout the universe. Essentially, as a result of the consistency of the fundamental rules and materials of the universe, we see the same structures and processes repeated countless times. This being the case, and if life isn't something "different" from the rest of the universe (as it doesn't appear to be) it could be that life is simply an inevitable result of the laws of our universe - a systematic progression from physics to chemistry to biology.
Personally, I wouldn't say that I "believe" that life must exist elsewhere, but based on this perspective, the size and age of the universe, and that nothing in the universe seems remotely unique, I certainly wouldn't be surprised if life is common.
Now, as far as intelligent life, as we perceive it, it's more difficult to say, as the specific variables involved in an evolutionary process which would result in such a configuration are necessarily far less likely, as life seems able to propagate just fine without such a complex development.
In your opinion, what "could" happen if the laws of physics were not constant throughout the universe? There are and have been observed studies that show/may show that the laws of physics are not fundamental and constant in all areas of the universe.
