“Chemical system” implies the need for the system to perform chemical processes to survive. The key word here is ‘systems’: the cells in your body are living, they perform respiration for example, but if they were taken out of you they’d die.
And finally “capable of Darwinian Evolution” simply means that the species of the system needs to be able to adapt through the changes of the environment and transmit those changes through reproduction.

Astrophysics has been proven since its inception that us humans are not special in the great scheme of things. We are not at the centre of the Solar System or the Milky Way or the Universe.
