Truly exist -- many things are understood without "truly existing". Blindness may be understood, even though light is perceived, and even if someone has never experienced blindness itself.
Is there any ontological existence in blindness?
Can you say blindness "truly exists"? Well, sure you can, since there are blind people. But do
you experience or know blindness at all, unless with your imagination? To you, blindness is more like a dream (a bad dream) than reality.
True existence is something that only
God may grant. Pink flying elephants may be understood, but they don't exist

. Likewise, Eä was understood before it was "willed" into existence. By your argument, this is impossible, and the vision brought before the
Valar was nonsensical.
"Understandability" is a feature of reality only in so far as God/
Eru wills it. There is no in-built rule in reality that demands it to be comprehensible. Einstein explained it quite well: the fact that the Universe is understandable, that it is liable to be studied by human reason, points strongly to the fact that there is a God. And even I, the staunchest evolutionist in this board

, can't see how natural selection would mould an organ (reason, not "brain") that is able to detect the order in the movement of stars and mathematics, without presupposing there is an order pre-existent. Why should there be one? If our reason is merely the product of natural selection, then so is our science and all of our knowledge, and therefore we can't trust any of it to be true.
(Including, of course, the conclusion that reason is merely the product of natural selection

).
Finally, what about
Manwë? Do you claim he does not exist in
Tolkien's myth? He does not understand
evil, he has no knowledge of evil. In our world, Manwë's role is assumed by the angels. (The real existence of angels is a side track. Luckily we are examining Tolkien's world here). If we must assume that Evil must exist or we would not understand or know it, I think this means that to Manwë it doesn't exist, since he fits these requirements.
And if something exists for some and not for others, I guess it is safe to say it does not "truly exists" -- just like blindness; or sight, for that matter!
(The matter of the true, ontological existence of things is a big investigation).
