I am not saying it's UFOs but many of the UFOs observed by the US Navy/Airforce were spotted on top of oceans and many have been reported to "disappear" into the ocean. The famous Tic-Tac UFO for example notably disappeared "into the ocean".

He said he'd love to see footage of something that is truly unexplainable. I mean who wouldn't.
The ocean also covers 75% of the earth.
So there’s a fairly high chance it’d occur over an ocean.
Unless you know more about UFOs than the rest of us, we have no basis to assume that it will appear above everything.
That said, this would be an interesting way to create an 'existence proof' of technological capability and presence if there was something about the holes that permitted ruling out animals or other natural phenomena.
Which is more believable?
