Translate from English into Latin: 'I just discovered you. Therefore you exist.'

JA pravedan prona?en te. Stoga te biti.

Is that Latin?

On the basis of "cogito ergo sum", it seems like the Latin would be something like
te reperio ergo ...  (I can't remember the 2nd person verb form  :-( )

wwwsurfer.ga has given a Romanian translation.

The Latin for
'Therefore you exist' is:
'Ergo es'.
(Myoarin, the present tense of the verb 'to be ['esse'] is sum, es
est, sumus estis sunt.
I'll look at the rest after my next class.

My translation:
'Hodie, te invenire. Ergo es.'

Hodie = today, or now. (One could use 'proxime' But 'hodie' seems more
idiomatic to me.)
'Te' = the accusative form of 'you' [tu, te, tui tibi te].
'Invenire' = first person perfect tense of 'invenio: to come upon,
find, meet with, discover or invent. I preferred 'invenio' to 'reperio
(to get again, find, discover) or 'disco (to learn, become acquainted
with) because it seems the best verb for describing a first meeting
with a person.
'Ergo' = Therefore
'Es' = you are (second person present tense of 'esse' the verb to be or to exist.

I hope this helps. I'm not a g@@gle researcher, so this is a free comment.

Amber,
I like that, hope Mike does too.

(Ceasar didn't use the second person very much, and I hardly got through the wars.)

Hodie, te invenire. Ergo es.

invenire is infinitive.
hodie is quote clearly "today" hoc-die -> to-day

I would suggest

Modo te invenii, ergo es.

I have just now found you, therefore you are.

'I iustus evestigatus vos. Proinde vos futurus'

'I iustus evestigatus vos. Proinde vos futurus'

That is evidently an automated translation, and has the typical
mis-understanding of machine-generated texts.

I->I missed to see that english I is pronoum, translated as number 1

just->iustus  Just translated as "righteous"

you->vos translated you (2nd person singular) as you (2nd person plural) 

futurus. futurus is a substantive meaning "thah wuill exist". How does
that apply here??

Having thought it over (and checking my Latin grammer), I believe that
Frox's translation is better than mine.
The Romanian one is just not Latin at all; and I entirely endorse
Frox's comments on the dreadful and incoherent automated version.
So, MikeKeller, go for Frox's translation.

te invenio, ergo es

How about that?  I think this is precisely "I discover you, so you exist."
It's short and doesn't add "today".
