But that doesn't mean there is a lowest most point in (0, 1] as any

I will not call any point but consider all points. There is no point

0 is smaller than all.

Note, I said between the point your THINK is the first, there is no

You can only have a first point in the open interval if the interval

No, that is your big mistake. In the interval [0, 1] there is a point
next to 0 and a point next to 1, and infinitely many are beteen them.

Define 'next' in this context.

The context is "continuous domains",
there are multiple models of continuous domains,
one of them is "iota-values" or "line-reals",
which is a model of a contiguity so fine as
a model of continuity, where it's, "EF(1)".

Of course, the models of continuous domains are
distinct as with regards to their definitions of
continuity and completeness of operations, so
it entails a bit of book-keeping to keep things.

Oh, you don't have one of those, ..., well, you
can always look to Aristotle, who has at least
two, and Zeno's always looking for how to arrive
at not being a fool, then fast-forward to Bishop
and Cheng who constructively go about making it
so, and for topology there's Vickers who helps
reflect that in topology there are various topologies
not necessarily the standard open topology, in case
you're thorough about these matters and want to
help square away various models of continuity,
continuous domains, continuous topologies their
own first and final, Cantor space, and law(s) of
large numbers.

What you said has no relation to the 'nextness' of elements in discrete sets. What is 'next' to Pi+2 in the reals?
