There's a mathemathical algorithm called STFT (Short Time Fourie Transform) that enables one to get the frequencies of soundwaves of a recording (a wav file), and their magnitudes, per time interval.
I ran this algorithm on the recordings of the names of Hebrew letters (Alef, Beth, etc).
Then I plotted a graph of the magnitudes of frequencies according to the time interval (Y is the frequencies, X is the time).
Then, using some very basic filtering, one can see that there are many recognizable shapes in each graph. What's special about those shapes is that in recordings of the word Alef, the shapes look like א, which is the shape of the Hebrew letter that is named Alef. Same goes for all the Hebrew letters.
Actually, any word in Hebrew creates shapes of a specific letter of the Hebrew alphabet, which makes the whole alphabet really special, as it conforms to the soundwaves of the words of the language. In addition, it is special that there's a complete match between the names of the letters and their shapes.
This is a copy paste of the description of the video:
1. There is a match between the names of Hebrew letters and their shapes in the frequencies graph of the soundwaves of the names.
2. The match could not be accidental because its probability is ridiculously low (much lower than 10^-25).
3. Which means that the one who matched the names of the Hebrew letters to their shapes knew how the frequencies graph of the soundwaves of the names looks like.
3. People, until recently, did not have computers.
4. Without a computer it is impossible to know how the frequencies graph of the soundwaves of the names of the Hebrew letters looks like.
5. So no person could make this match.
6. Under the assumption that either a person or God made the match between the names and the shapes of the Hebrew letters, this proves that God made the match, which proves that God exists of course.
7. People know about that match.
8. This proves that God told people about the names of the letters or about their shapes (or both).
9. Which proves the existence of prophecy - there had to be at least one prophet that heard about the names or shapes of the Hebrew letters (or both) from God .
10. This kills atheism.
This is of course just a summary. The rest is found in the video itself
