What Happened to the Sunken City of Cuba?

[Mystic Wanderer]

They say these structures are to deep to ever have been above water!! 

Apparently, "THEY" don't know what they're talking about.

Either these cities were built during a time when the earth was above water, or else there was a civilization who lived in the ocean who built the city. It has to be one or the other, right?

I haven't watched the videos yet, but it sounds interesting.  I'll put them on my list for this weekend.
