My point was, does the weed know it's alive? Or the Coral Reef? Who's to say, right? Now who's to say the Earth isn't alive? Just because it doesn't have a brain doesn't mean it doesn't live...
You honestly can't see how the Earth is a living system? Weather patterns, Sea currents, Molten Core, Tectonic Activity, Volcanic Activity, Ice Caps which grow and recede, Rock - into dirt - which plants use, along with sunlight to create oxygen for the rest of life to survive? I have made the list considerably shorter for the thread's good. But without this SYSTEM acting around the planet, WE cease to exsist, PERIOD. Take it away, and let's just say, take a look at the planet MARS...
Its streams are its veins, and Rivers are its arteries. The water itself creates life. You are thinking in a sense of Carbon Based lifeforms which is all that exsists on this planet...And that is okay, but you limit yourself. There are more possiblilities for "Types" of life out there. Carbon is just one. Silicon is another. And so on. IT'S AN ECO "SYSTEM", the Earth. A living system which sustains itself by depending on everything that is in it (plants, animals, dirt, rock, oceans, seas, ice caps...etc.). Without it, we die, along with everything else. IT IS A LIVING SYSTEM.
You fail to see the difference between a Living System, and a Living Thing. A weed is a Living Thing. The Earth, and yes indeed the universe, is a LIVING SYSTEM.

LB, while the Earth is an integrated system of living things, you are stating that is a akin to a biological entity like a human, a weed, a plant etc and that a LIVING SYSTEM is a LIVING THING. It is in fact it is none of these things. The dichotomy that you and hyperactive are pressing is false. In fact to use your new definition of life, my mountain of rocks (a subset of the earth with its own complexities), the flame, my SUV, or a virus for that matter is somehow aware of it's surrounding like a biological entity. But you two keep rejecting my examples of LIVING SYSTEMS! I wonder why? I am just using your new definition of a living system is a living thing. Thus, the flame is alive, my SUV is alive and so too are the mountain of rocks.
Using the terminology of "living system" does not change the inference you are making that it is a "living thing." In fact, all you two are really left with is some is an
ad hoc argument that the only way that this is true is only true in this case.
Moving on to your analogy of the earth with its
"streams like veins, and rivers like atreries." While its a wonderful analogy, it is only an analogy. We have yet to discover silicon based life and that's what this new definition of life, the Earth would have to be. With this
non sequitur aside, you can not make the case that while the Earth contains an Eco-system is a similar "living-thing" like a weed, plant, etc.

alas, no insult intended, but i think you do not fully understand systems theory and its implications. We can not rely on rigid axiomatic logic to explain the universe.
