At least in theory, given the right conditions and chemicals, life can arise relatively easily. This also assumes life at least somewhat similar to ours. That is to say, that these are life forms made of matter and uses chemical processes (particularly carbon or maybe silicon-based) to thrive as opposed to something more exotic, like a life form based on complex magnetic and plasma interactions. This is why Mars and several ice moons around Saturn and Jupiter (among others) in our solar system my have simple (microbal) life forms and possibly even more complex ones.
Venus, like Mars, may have even had a liquid water ocean at some point before the entire planet literally went to hell (for a number of reasons I won't get into) so even Venus may have had life on it at some point. If the conditions that caused Venus' runaway green house effect occurred gradually enough, there may even be some extremophiles still on its surface or in its upper atmosphere above the sulpher clouds.
If you consider the totality of the universe, the possibility of non-earth-based life has an extreme mathmatical likelihood.
The real question at this point isn't if there is life out there, but rather the question of how common life - especially life with humanlike intelligence and technological capability - actually is in the cosmos.
THAT is definately something that would be interesting (not that a more mundane form of exobiology would be - it would definatley be interesting to find an ocean filled with fully evolved life forms in Europa or even a higher life form in one of titan's methane oceans or surface or something similar in another solar system.
If today you can take a thing like evolution and make it a crime to teach in the public schools, tomorrow you can make it a crime to teach it in the private schools and next year you can make it a crime to teach it to the hustings or in the church. At the next session you may ban books and the newspapers...
Ignorance and fanaticism are ever busy and need feeding. Always feeding and gloating for more. Today it is the public school teachers; tomorrow the private. The next day the preachers and the lecturers, the magazines, the books, the newspapers. After a while, Your Honor, it is the setting of man against man and creed against creed until with flying banners and beating drums we are marching backward to the glorious ages of the sixteenth centry when bigots lighted fagots to burn the men who dared to bring any intelligence and enlightenment and culture to the human mind. ~Clarence Darrow, at the Scopes Monkey Trial, 1925
Politics is supposed to be the second-oldest profession. I have come to realize that it bears a very close resemblance to the first. ~Ronald Reagan
