Creation VS Evolution - Printable Version

I feel like posting a wall of my opinion

We, as a race, regardless of how we got to where we are, sit nicely atop the food chain in our ecosystem. But we consume and destroy more than we return to the source upon which we take from; this makes me feel like the race is akin to a parasite on the planet. But i digress.
In a tiny, far flung world in a rather bland solar system sits earth. The conditions that arose for intelligence in humans can be identified to an increase in fat in the early proto-human diet, which led to a more developed capacity for thought and logic. But consider the amount of time we have inhabited this blue rock versus the dinosaurs that existed before us. Account for the time in which they existed in which the potentiality for other worlds out there to have fallen into that goldilocks zone in their respective systems. Consider the likelihood that these planets wouldn't befall a world shattering event, which harms my mind to try and figure out (because let's face it i'm not that smart). Then try to figure out how their society might have functioned; the primary purpose of any species is to propagate. There are multitude of ways which this can be done, but ultimately every species wishes to spread themselves everywhere they can survive. If the environment changes, either the species adapts and flourishes, or is incapable and dies off. Now how many civilizations would have made it through any possible cataclysm to the host planet to develop the opportunity for intelligence. Then look at it from a social-studies perspective (a.k.a. the science of people and society. Forget what it's called atm). How do races which come into conflict with one another handle the situation? The two (or more) opposing species will either unify to strengthen the overall species, or try to wipe the other out to eliminate a potential risk to their propagation. All the while this is going on, the world around them continues to change.
For the sheer scope of the numbers these things bring to mind I find it very, very likely that if there is intelligent life somewhere in the universe, one of two possibilities exist: either a) they existed once in the past and were wiped out for another reason entirely, or b) if said species is still alive somewhere in the universe, which remember the sheer size of, it is maybe one of only a dozen, or even less than a dozen of species in the universe to have intelligence.
