um, no. that isnt actually possible, due to the fact that i am sitting here. and i am actually sitting here. existance isnt merely for the benifit of consciousness. if in basquillions of year creature come to this exact spot that i am sitting and find no remains of me or my building site house, it doesnt mean i was never here. creatures may have existed on this planet or other places that we know nothing about, that our arrogance cant conceive of, so *to us *they have never existed, but it doesnt mean that they have *actually never existed. *
There is absolutely no way of knowing this, though. Quantum physics tells us that the act of observation has a quantifiable effect on the thing observed, so your statement "existance isnt merely for the benifit of consciousness" (sic) is a bit simplistic – we simply don't know the extent to which 'reality' is a construct that emerges somewhere between phenomenological perception, or our sense-data if you like, and the materiality of the world around us.
