Before the number 666 was corrupted by (((them))) it was a holy number. In my opinion it shows the knwoledge of carbon-based life (we and everything here). 6 protons, 6 neutrons, 6 electrons.
Cicada let us dig deeper and has shown us, that ancient cultures had very detailed knwoledge about in vitro fertilization, chromosomes and dna. I think I can prove it.
But it's too much and a little too off topic for this thread.
