I am not the person you responded to, but I generally agree with them.
I guess they prefer to take an extreme Darwinian view. Since complexity is not the goal of life, merely a side-effect, there is no life on this planet that is more advanced than any other. Assuming a single abiogenesis event, all extant life has been evolving for approximately 3.8B years.
We may choose to think of brains, and our human brains in particular, as the bees-knees. Objectively, they are not though. Just one of many successful branches of the tree of life.
