Frank Drake, in the early 1960s, came up with an equation (called the "Drake Equation") that calculated the possibility of extraterrestrial life. He determined that there was a possibility of 100,000 to 1,000,000 extraterrestrial civilizations in our galaxy (the Milky Way) alone. With so many complex and huge solar systems across the galaxy, the Earth cannot be the centre of the universe. Because if it is then what is the purpose of the rest of the huge universe?
It is interesting to note the connection between the five-sided pyramid on Mars and the Great Pyramid at Giza. Alan F. Alford in one of his books has demonstrated how its chambers, passages and shafts could have formed the functional component of a hydrogen gas power generator, fuelled by water after being split into its basic elements. It has now been scientifically proven that Mars also had abundance of water in the bygone era. So it is possible that both the pyramids of Mars and Earth were huge energy devices with multi-functional purposes.
Pyramids stand out in a lot of ways and have astounded scientists for ages, allowing research to focus on them. But besides, this wonder, many parts of the world are sprayed with remnants of alien or strange people. A mysterious rock carving near Navai, Uzbekistan, estimated to be 3000 years old, has images of men wearing respirators. Could the object with rays be a space rocket? Then, in the ancient cave painting in the Prince Regent Valley in Kimberleys in Australia, a figure wearing a helmet with antenna is shown - an alien? Nearly all myths and folklore are full of tales of flying objects. Even if it were all pure imagination, they would have had to get the notion from some where. The story behind the rise of Dalai Lama and where he got his powers from also talks of extraterrestrial transferring their knowledge to humans.
We live in a three dimensional world with time being termed as the fourth, but why should we suppose that any living being in any other planet has to be in these dimensions only. Maybe there are more dimensions, complimenting their existence in their world. The probabilities are endless.
There have been media reports suggesting that various governments, with the USA topping the list, have been trying to hide and cover up the presence of extraterrestrial from the public. It will probably take some more time and more public reception and participation to determine the truth. If there are extraterrestrial, then we have already lost a lot of time by not accepting their presence. There's truth waiting to be discovered outside the circle of our compact lives. If only we would open up to the possibility that we might not be alone in this huge universe.
