"I disagree, earth sustains life with life, how is that not alive??"

"Earth" does NOT "sustain life with life", (if anything you would say that the SUN sustains life with radiation, does that make the sun alive too?) The "Earth" doesn't "do" anything the laws of physics "do" everything. The Earth is just another planet like Mars, Venus etc. etc.

"the earth has everything to do w/life"

Ok...

"if the earth was just a rock and couldnt sustain life"

Right, but if it were a bunch of rocks with a whole load of chemical and physical processes going on (which it is) it would.

"the things that the earth has done over eons of time has helped every living thing on the planet"

The "Earth" has not "done" anything, the laws of PHYSICS and CHEMISTRY have shaped the Earth, and as such have created an environment where it was possible for life to form.

"now does the earth have conciousness...?"

No.
