alt Hacker NewsThis is a bad explanation (or a non-explanation).
1. Why exactly life is attempting to build complex structures? 2. Why exactly life is evolving from primitive replicative molecules to more complex structures (which molecules on themselves are very complicated?) 3. Why and how did these extremely complicated replicative molecules form at all, from much more simple structures, to begin with?

These are natural outcomes of evolution, you see the same things pop up very easily with simulated evolution* of even non-organic structures.
* that is, make a design (by any method including literally randomly), replicate it imperfectly m times, sort by "best" according to some fitness function (which for us is something we like, for nature it's just survival to reproductive age), pick best n, mix and match, repeat
There doesn't need to be a "why?", we just need an absence of a "why not?".
Something as simple as the game of life shows you how highly complex emergent behaviour can emerge from incredibly simple rules.
