Is it enough for something to exist in order for that something to become real?

Existence = “The fact or state of living or having objective reality.”
Real = “Actually existing as a thing or occurring in fact; not imagined or supposed.”

Ooops!

Do I sense a conundrum haunting these premises?

Which came first? Reality or ‘mere’ existence?

Descartes was the first who had introduced a ‘pecking order’ into this mess.

Dubito ergo cogito.
Cogito ergo sum.

You’re free to translate this any way you want.
Mine goes like this:

My existence is certified only by my doubts.

My existence as a human being, of course.
As a conscious human!

The ‘pecking order’ being, as far as I figure it out:

I need to exist, as an animal, in order to become conscious.
And I need to gain consciousness in order to learn about my existence.

Complicated?
Let me elaborate.

Our understanding of the world is incomplete.
First of all, there are so many things we don’t know about.

For example, we have no idea what goes on between Mars and Jupiter.
We think we know that there’s no major planet hidden in between those two orbits. No object with an important enough mass to disturb either Mars or Jupiter and no object with an albedo big enough to be noticed. To be noticed by us…
Other than that… we have no clue about what’s going on there.
In fact, we don’t know much about what’s going on in the middle of our own planet… or on the floor of ‘our’ oceans…

But the fact that we don’t know about their existence doesn’t preclude the actual existence of whatever ‘objects’ and/or organisms might happen to be there.

Secondly, there are so many things we don’t fully understand. Not yet, anyway. We are aware of their existence – because we’ve been confronted with some ‘consequences’ of the aforementioned things, but we haven’t yet figured out, exactly, how those consequences have been produced.
For example, we’re still learning about viruses. About their ability to bypass our defenses. About how they infect us. About how we might improve our chances of avoiding/surviving infection.

But the fact that we don’t fully understand them doesn’t preclude us – well, some of us, from believing those viruses to be real.

My point being that ‘existence’ is far wider than ‘reality’.
There’s no need for us to know about it for something to exist.
But for something to be considered ‘real’, by us, that something needs to exist first.

‘But aren’t you contradicting yourself?
In a previous post, you argued that ‘the Flat Earth’ was real?!?’

Confusing, isn’t it?
I’m sorry if I misled you.
All I was trying to say was that ‘the Flat Earth’, as a concept, is ‘real’. In the sense that so many people discussing it – either for or against, make it real. Those very discussions, a direct consequence of the concept’s very existence – albeit only in the virtual space, give consistency to its reality.
Don’t get me wrong. The Earth – as I ‘know’ it, continues to be round. The Earth – that we live on, is not ‘Flat’. The Earth doesn’t exist as a flat object.

We are confronted with two facts here.
1. All that we’ve so far learned about it leads us to the conclusion that the Earth is, more or less, round.
2. There still are people who believe – or pretend to, that the Earth is flat.

The second fact exists.
The belief which made it possible is false. As far as we know. As far as the scientific community is convinced.
Yet the fact still remains.
Those people believing in it provide it with ‘existence’.
Those people believing in it make it ‘real’.

Sort of, anyway.
