Well read the hole story about the episode.  Iv had a suspicion about this the YT video talks about human biome which is bugs on our skin in our gut in our brains? Which can controll you bet you didnt know the reason the jews dont eat pork and why its the they torch the counter tops (stainless steel) for days all taking turns. Has the human race been compramised? Or are we in symbiosis with another species?  Perhaps both. What would you need to travel long distance over vast distances? Other then spaceship earth. Lifespan... dna protected? How, whats our blood have in common whats the oldest known living creature on earth?
