This is another great and very interesting post!
I am of the opinion that there were very advanced civilizations before some catastrophic event happened and wiped them out.
I think humans have started over many times throughout history for one reason or another.
Perhaps if we survive we will be able to either look back in time or even travel to the past. Maybe I will call it temporal - archeology.
Thanks, my friend!
