How can we be sure this is reality?

[Violet]

Everything exists. Everything is real.

Huh? No, and I am surprised to see you make such statement.

Mmm? Yes, and it really shouldn't surprise you to see me state things as they are.

Superman for example only exists as fiction, but not as a scientific reality. Not everything is real. Human credulity is and the ability to belief false things is, but pink unicorns are not real.

Superman 'only' exists as fiction. What are the acting bits? Oh, here's your sentence boiled down sans-qualifiers or quantifiers: Superman exists. You just affirmed what I said, regardless of your intention.

I don't give a rat's ass how 'little' or 'much' or 'in how many varied ways' superman exists: you cannot deny that superman exists, because superman exists. I mean... sure, deny that everything exists. That's logical

Maybe you'd look more favorably upon 'human credibility' if it were revealed to you that you take *everything you believe* on faith... on justified beliefs of varying 'quality', 'extent', or various 'evidences' which you've also taken (if but upon conjecture) to be true. While you blindly argue that something doesn't exist on grounds of how you perceive it to exist... we'll be discussing things of any particular interest, such as 'what does that perception entail' or 'in what form does one's perception exist' or even the basic premise at the start of the whole damn thing and forgetting the silly question of whether or not we exist (we do): 'how/in-what-way do we exist? Are we fiction or non-fiction (what is fiction?), are we material or immaterial? ARE WE DREAMING?'

“I dreamed I was a butterfly, flitting around in the sky; then I awoke. Now I wonder: Am I a man who dreamt of being a butterfly, or am I a butterfly dreaming that I am a man?” ~ Chuang Tzu

Women popping out of a man's rib is a real myth someone concocted but it is not a scientific reality, women do not pop out of men's ribs.

If you define scientific/materialistic realities as the only ones which are... you have made the use of the term pointless as it has been used in this discussion.

So even if I give you a silly understanding of a word: it would stop being applicable
