Would an Alien Language Be Written in Prime Numbers?

[I wrote this before I made the video above...I have lots more to say about this, but for now I'll leave this as is]

If we ever do encounter an extraterrestrial language, how will we ever be able to find a way to communicate with them? Some astrobiologists think we may be able to converse with ETs using a universal cosmic language based on prime numbers. Prime numbers are a very odd bunch of numbers with some very odd qualities.

A prime number, in case you were a bit fuzzy on it , is any number larger than one which is divisible only by itself and 1. So 2,3,5,7,11 are the first five prime numbers. As you can see, 2 is the only even number prime. Primes can have some very odd qualities.
