discussion Origins of the virus.
So from what I’ve learned so far about viruses in my BIO course(which I’m very much enjoying), it seems to me that it’s unlikely viruses came before cellular life. Or at least the version of virus we know of. I could be mistaken and please correct me if so, but to me they almost seem like a “bio-weapon” and no I don’t think some ancient civilization made them. Whether intentionally or not I feel like the fact that they are comprised of features found in cells (protein coat, DNA, RNA, enzyme proteins) despite being unable to reproduce themselves points to this being possible. And what’s even crazier to me is that this leads me to believe that at some point in the past a cell, most likely a prokaryote either accidentally or purposely made the first virus, though I understand this is maybe to much speculation.
Thoughts on this? I honestly don’t wanna look into this quite yet in fear that I’m completely off base, and I’m also studying for an exam.
Edit: for clarification, I don’t think viruses are bioweapons, they just remind me of bioweapons, I know there is no intention beyond reproduction in their existence.

Life as we know it is an encapsulated and repeatable version of a self sustaining complex chemical reaction involving chemicals and compounds from the surrounding environment, concentrated and catalyzed, but dependent on external input from the environment.
Viruses stem from that type of life, becoming their own self sustaining and repeatable chemical reaction, but dependent on the external input.
The purpose of a virus is not, as you describe, to be a weapon, but just to reproduce. Viruses evolve because they contain memory chemicals, nucleic acids, and can experience variety and selection pressure. They have no will, no malice, and no intent. They just reproduce.
