With how big the universe is I think it's almost a certainty some form of alien life exists. Whether it's "intelligent" or within a range that we could ever encounter it is another thing
There is a somewhat philosophical point that has been made about this by someone very much smarter than I. This may be conflating a few things, however without googling it, I recall it went something like this: that whether alien life exists/has existed is irrelevant due to the point that if life is in any way consistent across the universe, then it is very possible that they had, or will expire before becoming technologically advanced enough to be in a position to influence (via communication or other means) life on earth as we know it. Also something to do with our population on earth (as a yardstick perhaps) statistically suggesting the potential longevity of human (and alien) existence or some such. That is to say that if you pulled a little ball out of a jar containing an unknown quantity of balls in it, and it had the number 10 on it, you would not unreasonable think that there was perhaps a greater chance of there being maybe 15 balls in there rather than 15k balls. We are all around the 108 billion mark. How much longer do we need to become technologically advanced enough to explore the further reaches of the universe to find (or not) alien life? And additionally to the insight provided by @Angevin, after reaching such a degree of technological advancement to reach planet earth, what possibly could be found in a rednecks rectum that would be of any consequence to them?
Probability clearly is not my strong point, so my money is on yes and none of the aforementioned ideas are my own, but they sound good!
