Why was this program kept secret for so many years?

What did the Soviets discover under ground?

The secret Soviet drilling program started in 1970 and found surprising results that are now partially available online. The program, called Kola Ultradeep (or Superdeep), tried for many years to drill deeper than 12 km, but they could never get any deeper than that. There seems to be something preventing man from getting any deeper than 12 km. Could it be that God has set a limit on how deep we can go?

Kola Ultradeep made discoveries that put current geology models in question. Examples: the rock does not go from least dense on top of the crust to more dense under the crust. In fact, the rock is porous and holds water, all the way down to the deepest ever drilled. This helps explain the great flood and the account of Noah’s ark.
