Wondering, what are some of the uses for ada, what is it for, why is
it better than other languages.....this is.

Ada is for SW you want to be correct. It's better for me because it is a
language for SW engineers rather than for coders.

I use it for programming

Because I know it better than most other languages

Here are some: http://www.seas.gwu.edu/~mfeldman/ada-project-summary.html

Anything - from very serious things, to things not serious at all!

Is it ? Perhaps. For me it is the sum of many details which in total
make a big difference.
Generally, it is made to catch your errors the earliest possible. You
also notice potential errors more often. It begins with the fact that
you have:
...
end if;
end loop;
end if;
...
and not brackets. You even don't write some classic "banana skins" in
the first place: steps in the "for" instruction are only 1 or -1. Ada
offers plenty of attributes which make life easier as well: you'll
write "for i in x'Range loop" rather than having to pass a 'n' integer
and putting the wrong upper bound on your loop. And so on...

Then, features are fairly orthogonal.
- you are not forced to use references and pointers if you don't need
them. If you want, you can make a full object-oriented GUI without any
dynamic allocation on GUI objects.
- the type system is not bound to the modularity (package /= class)
- you can make "a:= b" whatever the complexity of a (and b's) type
- you write "if a = b then..." to compare two integers, or two
matrices, or anything else as well: for instance, the whole contents
of a dialog box before and after user changes, to check if there is
any.
- you have expressions for every type

Then, the nesting is very powerful in Ada. It's definitely not a
"flat" language.
You can have a package inside a function you need it. Define a local
procedure inside a loop. And so on.

Along the same thought, I like that in Ada one can easily define an
array to start from 0 instead from 1. Depending on the problem. This can
make the coding much simpler. (less chance of making one-off error).

In other languages, arrays starts from either 1 or 0.
