I think what they meant eternal is not the whole part more like just one piece of you living on for years would make you happy? Like how surnames that are usually known was kept in some countries to preserve their tradition, culture, etc. with just the thought of that, it would amazed the person to want to live like that, having something to pass on. While living eternally, alone or not, means you will preserve yourself as one and wjole, living eternal so to say.. well correct me if I'm wrong since it's just my own opinion and thoughts regarding this intriguing topic you brought up and I'm all open for advice, thoughts and feedbacks.

There was one question in the back of my mind when reading some of these, what exactly does it mean to be eternal? My head hurts. When people say we they will live through us, it really means their not eternal, someone living through something doesn't make it eternal, because that something could die too, even if they pass you through someone else, they'll never truly know you. So, is living forever really eternal?
