Geez, it's tiring repeating myself to you.
We don't have to, you've been shown beyond a reasonable doubt that the first texts where Hebrew. Let's review:
The Hebrews despised anything Greek and would not have allowed Greek texts inside their Holly places.
We have witness testimony that the original texts were indeed written in the Hebrew as listed upstream.
Thousands and thousands of Hebrew texts (likely many original Hebrew texts) were burned by the church, as evidenced by E-S above.
After the crucifixion, common sense would dictate the Pharisees would launch a campaign to destroy any written record of Yeshua's teachings.
Basing your theory on a few fragments of Greek texts, that everything documented was documented ONLY in the Greek language, is a ludicrous assumption.
