We don’t know. The earth is 4.5 billion or so years old...We have no idea what or who might have visited here long before man’s short time on this planet.
We all have our beliefs or opinions and on that one, I really have no hard opinion either way. Maybe, or maybe not would be my opinion regarding being visited.
“The earth is 4.5 billion or so years old...”
You’ve really gone and done it now!
