This is the nihilist/materialist rhetorical trap.
If you take scientific materialism to it's extreme 'we are all just particles' ergo, none of intelligence/life/love/wisdom/creation even really exist, it's all just how we perceive randomness.
'Sociopaths' and 'Psychopaths' cannot exist in materialism after all: we're just mounds of atoms.
But once you accept the life principle, which is not so well defined but nevertheless evident to us all at least due to the fact we are conscious ... well then you can start to arrive at why we might think we are 'more important' than rocks.
Then things like 'community' etc. make sense.
But one's metaphysical view needs to have something more transcendent that e=mc2 at the root of it in order for it to work.
The OP's comments are actually reasonable in the context of materialism, and that they are a little 'shocking' to someone normally engaged in life is only evidence of the hollowness of our current rational regimes at explaining the most basic question, which is 'who/what are we'. Knowing how 'dark matter' works will be nice, but it's still secondary to understanding the nature of life itself, I think.
