Soliton, youre like the three year old who has learned to constantly ask WHY? and consequently thinks himself to be just the most clever fellow around. You made an unqualified positive assertion and now you cant back it up. Of course, you knew you couldnt going in, but you figured yourself to be too clever a fellow to not be able to wiggle out. To wiggle out, youre now saying that you believe something (that no truth exists beyond your comprehension) about which you have no evidence (no rational cause to believe), and that you should not be held to the same standard you insist on imposing on everyone else.
The ball remains in your court, and you cant even clear the net.
You can not prove a negative. You can not prove that something does not exist. It is usually encumbent upon the person claiming something exists to supply evidence for believing in its existence.
