>You seen to think consciousness spawns from existence, if so what makes it not the other way around?

Are you conscious i.e. perceiving? Yes. If you did not exist you would not be doing anything e.g. perceiving i.e. being conscious. If you were a non-conscious thing, e.g. a rock, you would still exist. You cannot be a conscious rock that doesn't exist or a conscious person that doesn't exist because consciousness spawns from existence and not the other way around.

>Also implying "necessarily" is a myth?

I did not imply, I stated. "Necessity" is a myth we made up. It is a fictional relation. If you chain me up and tie me to the Titanic on the ocean floor, I can want air in order to breathe air and I can want air in order to avoid becoming a drowned corpse. I cannot "need" air in order to breathe air and I cannot "need" air in order to avoid becoming a drowned corpse anymore than a drowned corpse can "need" air in order to breathe air, "need" air in order to avoid becoming a living person or "need" air in order to become a magical unicorn with cybernetic wings that can time travel by absorbing yellow solar radiation or "need" air in order to avoid becoming a magical unicorn with cybernetic wings that can time travel by absorbing yellow solar radiation.

"Necessity" affects nothing except via the imagination, it never exists outside our imagination. It's just ego that the universe revolves around us so when we're chained to the Titanic we can do more than just want to survive, we can SOMEHOW "need" to survive. Reality is we never "need". We are all like a 120 year old man on his death bed riddled with cancer and we are all like an outwardly healthy-looking child diagnosed with terminal cancer.

>What ISN'T a myth?

At least seven things that I know of, six of them I can recall. I would remember the seventh but I have memory issues.

>Other than the consciousness, which, I will grant, for any purpose of discussion can be called a "doubter", by definition what does the doubter base it's Doubs upon?

Everything. You yourself gave four examples; coherence, your memory, the consistent world around me and your body itself. If you're trying to ask how doubting works, I've already covered that: That's us looking at patterns and consequences and meaning. That's consciousness perceiving. That's you going "What does this mean? What does this entail? What are the consequences here? What does studying the patterns reveal?"

>That is meaning, meaning is the base for doubting, at least that how I understand it, you might have a different definition I would like to understand it.

No, (in that regard at least) not a different definition. But, as I go into above, there is more to it than simply stating "meaning is the base for doubting". Also, you're contradicting your earlier thinking about "an unmeaningful world" since you've essentially just agreed to part of what I've been trying to explain: Doubting cannot be doubted hence meaning cannot be doubted.
