But it does add to my argument that plants are better than us =D

Then define this notion of "better" for me so that I can -fully- understand what you're trying to say.

I think what KT is trying to say is that we would be nowhere [cease to exist, or perhaps exist as something completely different but undoubtedly non-human.] without plants. Plants, however, would be somewhere without us. [probably similar to where they are now]

Can something completely dependent on another be considered greater?

I understand the words 'superior' and 'greater' etc are not valid scientific words. I am only contemplating perhaps the hierarchical levels we would place plants and animals on.
