I have some questions for the posters here.

Fine.  Then let me put it a different way.  You have given no valid argument justifying guessing, estimating, or having an opinion that your assertion is true.  Why should someone who doesn't share your view adopt your view?

I get it.  You think something is true that you have no good reason or argument to think is true.  All you've got is an incredulous assertion.  That and six bucks will get you a cup of coffee.

If all you've got is your assertion and your incredulity, your opinion on the matter is easily dismissed.  If you think you've justified your opinion, then you are wrong.

Do you think it's true that the assertion "There are no gods" is an assertion of such universal magnitude that there is no way to prove it?

Yes.

Then according to standard usage, you believe it. I get that you don't like the word believe, but your opinions don't dictate the meaning of a word; usage does.

Now, do you have a good justification for thinking that this is true? Your justifications so far have been invalid. Incredulity and ipse dixit arguments only suggest you're a bit unintelligent.

Why should someone who doesn't share your view adopt your view?
