Discourse on First Contact: Aliens are Likely to be Hostile [Continued]

Thank you for a timely response. I will concede that there is a probability for silicon or other such based lifeforms. Again, this is a debate of probability, not hard line truths. However, I would argue that point [1] out of my opening argument is universal for any form of life. If life does not seek self preservation, it ceases to exist. If life does not progress itself, procreate, or reproduce, it ceases to exist. Thus we can deduce that any form of life, no matter how advanced, has formed or evolved with a mechanism for self interest. It simply stands that every action an organism takes on this world is dictated by this fundamental tenant. ET will come here with interests of its own, that is an absolute. Otherwise, their is no motivation in which to do so. This is part of the reason that I argue pure altruism does not exist. There are always, and always will be, individual mandates that push us into selfless or selfish action. And if they do come here seeking something, be it knowledge, which I believe is unlikely, friendship, or resources, the technological gap would be so large we would not be talking in terms of canis to man, but ants to man. They would be light years ahead of is in terms of technology and science. "that's how we know life to work, but they most likely wouldn't have the same type of life as us." I would beg to differ. While we know silicon has the same propensity to bond into long chains or organic structures, it has a limited capacity to do so [Certain elements]. So far as we can deduce, carbon is best fit in biochemistry. Other findings from a lab also indicate that carbon based life forms best in conditions similar to our current situation: Earth. This means the odds are in the favor of carbon based life so far, which is best suited for environments similar to ours. This in itself dictates that most life would arise in a similar fashion to ourselves. In saying this, there are any number of scientific findings to come about in the future that could completely change our understanding of biology and biochemistry, but at the moment life has the highest probability to arise in a similar fashion to our own. Just to clarify, carbon can either lose 4 or gain 4 valence electrons to form a stable covalent bond. This lets it bond with most everything on the PT and itself, into long complex chains. So far no other element has matched its capability to do so. 'Trying to make ourselves invisible would just delay the inevitable. It doesn't matter if the come in 20 or 20,000,000 years, they will still be 100 times more advanced technologically than we are. Why make ourselves look like a threat when we can show that we mean no harm?' Perhaps, but technology can only progress so far. There is a theoretical limit to how far up the food chain a species can progress. But I think we already make ourselves look threatening if we possibly could. We are such a war plagued species, full of violence and unrest, perhaps it is WE who are not ready to venture out into the obsidian abyss. But secreting ourselves away buys us time to either destroy ourselves or resolve most of our internal discrepancies [I believe war will accompany humanity until the very end]. In doing so we may make ourselves better suited for a first contact scenario, technologically or psychologically.
