Actually, it is a UFO. I know because I remote viewed it.

Those ARE fireplaces on the roof of the UFO. Ancient aliens flew here from thousands of light years eons ago so they could kill a few wooly mammoths and snow bison. Earth was a huge game preserve maintained for the well-to-do aliens from Beta Retuculi.

After a very successful hunt in 186,933 BC, the aliens got drunk and made fireplaces on top of their spaceship, drank a lot more beer and enjoyed a fine Wooly Mammoth steak. Some in their party wanted to go fishing so they went on a whaling expedition for Beluga Whales there in the Baltic Sea. That is why they parked the spaceship in the ocean.

Unfortunately, the pumps on that particular spaceship were not operating that well and the spaceship sank during the night while the aliens were passed out from all the alcohol. They were washed overboard and lost at sea, kind of like an early version of the Titanic disaster.

Meanwhile, back on land, early Russian cavemen who witnessed this entire event made cave drawings of what they saw, like a record they wanted to preserve for future generations.

The reason TV’s and cellphones do not work in the vicinity of the sunken spaceship(there, I said it) is because the electro magnetic fields produced by the nuclear Geodyne plasma engines within the spaceship, are still emitting a “time bending” aura that picks up the signals and deposits them into the future. In laymen’s terms, they are actually working but the signals from say, cellphones, are transmitted into the distant future.

The ship is actually made of concrete. Weight is not an issue with these aliens with their superior technology and it affords the best protection from harmful gamma rays and radiation while they are sporting around and through the galaxy.
