How many civilizations are in the Universe?
Now it is accepted that major part of the stars have planets. The spectroscopy assures us that water and the basic components of carbonic life, including amino acids, are everywhere in Cosmos. More and more specialists admit that the germs of life are traveling throughout the space, „infecting” immediately all appropriate places. If the favorable conditions last several billion years, life can reach the abundance and complexity we see on our Earth. In some cases such a complex life system can give rise to a „technological civilization”, that means to intelligent beings capable to build spaceships to conquer other inhabitable planets.

In 1973, in Romania, in the heart of Transylvania, near the town Aiud, workers extracting sand from a quarry not far from the river Mures, found, at the bottom of the excavated bank, a strange aluminum object whose properties have not been explained.There were three hard bodies, „packaged” like in a shell of hardened sand. They had stood a long, long time beneath that – almost 10 meters thick – layer, deposited over time overhead.
A specialist was called urgently to the sand career to identify the bodies. In two of them he found fossil bones; and in the third, something that seemed, by the shape and weight to be a stone ax that would be served primitive man in killing the animal whose bones were found together. For a proper study, the three items were sent to the History Museum at the city of Cluj-Napoca.
Carefully removing the surrounding petrified sand layers, the specialists found a piece of a leg bone and a piece of tooth, both of a young mastodon, and a totally unknown object, which was not in any case an ax and was not even from stone: it was metal! Detailed analysis has had to offer but more interesting surprises.
The object, about 20 centimeters long, 12.5 centimeters wide and about 7 centimeters thick, had two cylindrical holes, of different diameters, so that the narrow hole penetrates the object toward the base of the larger hole in a perpendicular way. Moreover, the larger hole had in its lower part a chamber as for assembling a rounded axle head in it. On its lower surface and in sides the object showed traces of repeated blows, some of which were strong. All details suggested that it was once part of a bigger device and was lost for one reason or another, in the river bed.
