What could be

Who really knows what happened in the past, and by past I mean before recorded history on the order of 10,000 BCE to around 500,000 BCE.  There is some evidence lying under the oceans and large bodies of water like the Mediterranean and Black Seas.  Tantalizing artifacts and stone pyramid structures have been filmed.  If it turns out to be true that civilizations existed that far back in time, then we moderns have a lot of adjustments to make.

The Earth has it in its nature to hide what has come before.  And, it can hide it in ways that can never be found.  So, it's highly unlikely that humans today or going forward will find physical evidence of the civilizations that have preceded recorded history.

I wish we could actually know what happened.  It could mean that we would find our origins.  It might mean that our civilization would make quantum strides toward some way of breaking out of our own solar system like the movie Interstellar suggests.  I do wonder about the ancient world, but the Earth's lips are sealed.  In the meantime, I just have to live in wonder.  But that wonder keeps my imagination alive.  And it is in the imaginative world that I can truly have happiness and construct scenarios of what could be.
