Comets leave in their wake trails of rocky material, the source of annual meteor showers on Earth. As the rocks burn up in Earth's atmosphere some wonder if the intense heat destroy any organics within the rocks? Apparently not, says NASA astro-biologist Peter Jenniskens. He and his team of researchers observed the Leonids meteor shower from aboard aircraft. Jenniskens has announced that much of the organic material in the rocks appears to have survived entry into the Earth's atmosphere. Life's components have come from space on Earth just as they have done so on other planets. The cosmos shares the same gene pool. Therefore it is not surprising that some species are similar even on planets light years away from each other. However since the possible varieties, especially of plant and animal life is vast, different species show up on different planets. Nevertheless, since the so-called intelligent species in the universe are limited, there is greater likelihood of finding the same intelligent species, such as humans in several planets of the cosmos, as well as intermediate species that lead to the creation of a human.
Since the difference between a human and the animal that precedes it imply only a small increase in genes, the first humans to appear on a planet are only slightly different from animals. The major difference is that a human has more versatile vocal apparatus so that his language is more elaborate than that of an animal. He has more dexterous hands as well so that the use of tools to help him in his daily life comes more naturally to him than it would to animals. A bigger brain allows even the most primitive human to appreciate the rudiments of art such as body paint and ornaments that an animal would consider scandalous encumbrances. However, in spite of these significant differences the most primitive human still remains close to animals. True he builds some mud or thatch shelter, but even birds do that better even without the use of hands and tools. It is also true that even the most primitive human can learn elements of an advanced culture such as reading and writing if urged and trained to do so, but then animals too, such as dogs and monkeys can be taught a lot of tricks given enough patience.
Along with genes comes an element of genetic memory( to be more precise spiritual memory ) that urges species to repeat what they have known before. At a certain stage of further evolution human groups that race ahead in genetic evolutionary development are prompted to rediscover writing, numbers and the science of mathematics. It has happened on earth from time to time, to Sumerians, Egyptians, Aryans, Mongoloids, Greeks, Romans, Europeans and so on. Such groups surge ahead in their development and are able to spread the skills to their less advanced human cousins as well, so that the less endowed groups may carry on with some development too, albeit in a messy sort of a way. Further development leads to higher values of discipline, organization, philosophy, morality, science, freedom of the individual, and the arts. At a certain stage of development humans learn about the genetic code, and learn to manipulate it so that they may improve upon their own physical apparatus, food sources as well as other species on their planets. This is the point when they begin approaching their intended creation in the image of the Gods, for now they contribute to the work of Gods through Intelligent Design.
