Scientists say it could take at least 1,500 years before humans make contact with species of aliens, or for them to communicate with or find us. Astronomers from Cornell University in the USA combined two existing theories about the possibility of life existing on other planets to form a new equation. One of these theories is the Fermi Paradox described by physicist Enrico Fermi in 1950. This States that while billlons of Earth-like planets exist in our galaxy, not One has made contact with Earth yet. The other is the principle, which suggests that because there is life on Earth, it will typically exist on Earth-like planets throughout the universe. We havent heard from aliens yet, as space is a big place, but that doesnt mean no one is out there, study author and Cornell astronomy student Evan Solomonides said. According to Solomonides, extraterrestrials could have received signals from Earth. However, he suggests that ET would not have been able to decode them. He said they would need to decode the light waves into sounds and analyse 3,000 human languages to understand any messages. He said that signals from Earth have only reached about 8,500 stars and that the Milky Way galaxy alone contains 200 billion stars. He added: If we stop listening or looking, we may miss the signals, so we should keep looking.

Humans have much in common with to other live forms on Earth. Since the very a first live form appeard, all living things have been desperately struggling to survive the harsh and changing conditions of our planet. This has involved adapting to new situations and in many cases has led to either evolution or the extinction. We are not alone in making use of the world around us (birds use twings to build up nests, for another example) or in being particularly skillful (spiders make intricate webs). Where we do differ from other life forms; however, it is in our ability to record and learn from our collective history. In this, it appears that we are unique. There is still too much mankind does not know about the earliest humans, of course not, but we are increasingly becoming a species with detailed knowledge that about our past. The more we learn from, the betterare our chances of survival in the future. It must also me recognized; however, that we are also the only species on Earth in which has managed to createthe mean of destroy the planet we live on.

Unlike buried treasure and some minerals, fossils are usually not valuable in themselves. However, most of the fossils you find will be of greatest value to you. They will help you learn much about the geologic history of the earth and its inhabitants. If it were not for fossils, we would have no way of knowing about the animals that once roamed the earth or that once crawled on the bottom of the ancient seas.

Unlike buried treasure and some minerals, fossils are usually not valuable in themselves. However, most of the fossils you find will be of greatest value to you. They will help you learn much about the geologic history of the earth and its inhabitants.

If it were not for fossils, we would have no way of knowing about the animals that once roamed the earth or that once crawled on the bottom of the ancient seas. In fact, we would not even know for sure that there were once seas in some regions if it were not for the many fossils of sea animals that we find there.

You can look at some fossils and see for yourself the shape of the ancient animals. Even if you collect only bits of one kind of fossil, you may still be able to tell what it looked like. Making sense out of fossil bits is a little like working a jigsaw puzzle. Sometimes you will lose pieces, but you can still recognize the picture and even use your imagination to fill in missing details. The habits of ancient sea animals are not so easy to determine. Therefore, scientists study the structure and the habits of similar living animals to learn what the ancient ones must have been like. There are some things, however, that neither the study of fossils nor the study of living animals can tell us. For example, no one knows what colour most ancient sea animals were. Also, since the soft parts disappeared soon after death, many details of their internal structure are unknown. So the pictures of ancient sea creatures (as well as dinosaurs!) are what scientists think the animals looked like. Reconstructing the life of an ancient sea animal on the basis of fossil evidence and the characteristics of similar living animals is a little like relying on circumstantial evidence in court.
