Do we really exist?

Question:

Do we really exist?

Ok bhuddists think life is an illusion.... but this is supported mathematically our mass compared to the mass of the universe is well its small so small a number in fact any mathematician would round it to zero.

So if we dont have a mass then what are we? Are we simply figments of someone elses imagination that doesn't exist?

If someone (who didn't exist) chopped a tree down (that didnt exist) in a forest (that didnt exist) with nobody (that didnt exist) around to hear it would it make a non existent sound?

Ken u have made remember a whacky old professor at uni that said to us.

"Whenever we try to measure any system in some way we add an element to the system and then it is no longer the original system. I wonder if we are just making it up as we go along."

If you consider the mathematical assumption difficult to swallow consider this. If you compared the error associated with it to the error associated with the assumptions applied in the design of (non-existent planes) then that error to would be so insignificant you would either have to accept it or accept that planes (that don't exist) can't fly. As by comparison the error associated with the design of a plane would be almost infintely huge.
