"If life is to be found anywhere, in our system or beyond, we would probably kill it 1st in the name of science, then well just because....whatever reason. Until we humans get beyond our own need for violence here on mother earth, we should leave alone."
This got me thinking about how ridiculous that sounded, and sadly there were other posts that reflected this Star Trekian notion of the "Prime Directive", where we should not interact with any life we do find. How then, are we supposed to learn about it? We're not to the point technologically where we can "scan the planet" and know everything we need to know. Maybe one day, but not now. For now, we are very much at a hands on, get down there and grab it level. So, this is what I wrote back to him...
You're talking about changing human nature, and the act of survival at its most primal level involves violence. Kill or be killed. Humans are still animals. We may be the most advanced animals with the ability to reason and apply logic to multiple ends, but the core of our being is still primal. Regardless of our egos and hubris, we are nothing more than advanced animals.
This is why we fight for mates, fight for possessions and fight to exist. Yes, there are those who fight to be bastards, but do you think we can breed any of this out of us? I think not, and I wouldn't want too. The ability to defend oneself from a potential foe is paramount to maintaining our existence. There will come a time when we will find other cultures in space that will most likely be hostile, and heaven forbid we pussify ourselves to the point that they just dominate us without an ounce of resistance on our part.
Our goal is not to kill the life we seek, but to learn about it and from it. Will we and the other life have coexisting issues, and possibly cause harm to each other unintentionally? I bet so. Nevertheless, that doesn't mean we have to remain in our cradle, afraid to crawl into the cosmos.
