The humans living in the Ukraine near Kiev about 15,000 years ago:
"The oldest house in the world is approximately 15,000 years old and made of mammoth bones, found at Mezhirich near Kiev in Ukraine. It was probably covered with mammoth hides. The house was discovered in 1965 by a farmer digging a new basement six feet below the ground. A similar house can be seen in the movie 10,000 B.C.[2]" ****
