Also, given the conditions of our universe, I think life on other planets is pretty much inevitable. After all, we are here, aren't we? And there are solar systems out there with conditions far more favorable to life than our own solar system is.
How do you know Earth isn't the height of perfect conditions? Until we fine another planet with life, we only have ourselves to compare to, so for all intents and purposes, we are 1 for 1, the only know planet with the proper conditions for life, and the best planet for life.
For the record, I do believe there is other life out there, but I am just thinking realistically about the current known reality.
The height of perfect conditions? With all due respect, considering how easily it is to be killed by almost anything on this planet, whether it's by storms or volcanic eruptions or earthquakes or tsunamis or what have you, I highly doubt our planet can be considered the "height of perfect conditions" for life. Sure, we've got a lot of good things going for us here, favorable enough for life to evolve substantially over billions of years rather than being constantly being wiped out by asteroid impacts and whatnot, but we mustn't forget that we're not living in some paradise with everything correctly engineered in our favor. We exist because life repeatedly and persistently adapts, even in the most extreme conditions, whether it's at the very bottom of an ocean in a hydrothermal vent or at the top of a frozen mountain peak and everywhere in between.
Basically, by our current known reality, where life can exist, life
does exist, and it springs up almost as soon as the right conditions for life are met in an environment, much as it did right here on Earth. There have been some interesting studies done in the past few years that show life existed on Earth much earlier than previously thought, even in its most hostile early stages of formation, which is a testament to how enduring life can be, even in conditions that would seem highly unfavorable for life.
Also to be considered: We're carbon-based lifeforms made out of some of the most common, most ordinary, most blatantly abundant material strewn across our universe. It's not like we're made out of anything special that can only be found here on this little planet of ours. The ingredients for life are everywhere, just waiting to come together given the right circumstances. And we don't even know what different types of lifeforms may be possible yet. There could be silicon-based lifeforms that exist in conditions we never thought possible for life somewhere out there.
Sorry for the wall-of-text response. The gist of it is this: realistically saying we're the only life in the universe because so far we've only found ourselves is like someone saying the Earth is the only planet in the universe because they don't have the means to see there are other planets out there yet.
I firmly believe that as our technology continues advancing and we keep exploring out into the depths of space, we will find at least some shred of evidence that life can and does exist elsewhere, whether it's a dusty fossil buried in Martian dirt, actual aquatic life swimming beneath the frozen surface of Europa, or chemical compositions indicating life observed on a planet far beyond our Solar System. It's just going to take some time, patience and hard work to get that far.
