Might Aliens live among us?

 

The earth has existed for quite some time and the possibility that there could be aliens among us is not so far fetched in some respects. When you consider that the earth was formed 4.5 million years and then has been 600 million years the rubble has been formed and has been a steady growth and evolution. One theory says that if there is an organism that led to the land before time? The earth before humans and life as we know, before the animals and even plants? When the earth was not the Baron and yet have an abundant life in it.This may sound silly or absurd in some respects. However, when one thinks about the life of the earth and the many different variations of human beings, animals and plants that currently exist and have existed in the past. It's really not as crazy as it sounds. Another who could have their biochemistry and developed out of what remained after the human and animal use. Like humans, animals and plants adapt to their surroundings and the environment, so you might another form of life. They could also need the same things we need to live, if that was true again living among us can not be so farfetched when many places uninhabitable parts of the world for humans and animals, but perhaps not for another being.A scientist named Benner believes there could be organisms that live among us today. That are not based on DNA and could be more primitive in their biochemistry. Some researchers believe that life based on DNA came from RNA-based life. Both RNA life stores genetic information, but behaves like an enzyme. Benner believes that this life of RNA around 4 billion years lived on earth. That made grown food, play, and has evolved over time and learned to switch to double-stranded DNA to carry genes. The evidence says that it is in our own genes.Of course, one obvious way I could have survived would live in areas that the DNA-based life can not live in would be a niche agency, but would be much smaller than the DNA-based life, allowing them to fit in areas such as the rock pores. RNA life could be flourishing today and did not even know it. A good example is look at a teaspoon of soil, water or air and all the DNA extraction and reconstruction of genes and genomes of all species.The idea of ​​another life among us, interesting and a little unsettling. Thinking that life could be the evolution of others and not even know it sounds a little strange. However, at the same time, who knows if they have evolved and gradually incorporated with us. There are many people out there who want to believe in life on other planets and there are UFOs and aliens out there, this may be just what you are looking for.
