>>The universe and us are one and the same – there is no us without it, there is no it without us

That’s not what I mean – the universe would undoubtably exist without us in the future. But we are a creation of the universe in the same way the stars and galaxies are. And yet, short of other life, there is nothing about the stars or galaxies that means they can make value judgements about significance.
As for other life, yes – it would experience the universe. There’s nothing to suggest that it would ascribe value to it in the way we do. Equally, there’s nothing to suggest that it wouldn’t – but given the sheer number of variables I would suggest it is unlikely that other life will be the same as us.
Concerning our destruction tendencies – as a living system we consistently increase the entropy of our surroundings to minimise the entropy within our own system. As life brings an entropy increase within the walls of its own system, the net entropy increase of the universe is minimised through life.
The sun doesn’t do this.
And anyway – significance is only a system of classification, a lazy and simple comparison between different things. Why is significance significant? ;)
