Life; refers to be alive. We live on our planet i.e. earth. Do you know why we live here? Because we have been created on it and it has all living conditions. However, in our universe several other planets exist as well. Human's mind and psyche force him to think about these planets and know whether life exists on them or not?

Life existence on other worlds means they have some source of revenues as well. Man began exploring life signs on other planets a few years ago. Surprisingly, he got slight verve indications there. However, the information is not now shared with common public yet.

For instance, oxygen gas is compulsory for life to exist anywhere. It has been proved through a number of surveys that verve is not possible without oxygen. So, if we realize some signs of life on other worlds, that means they must have oxygen there turning around. For the same course, scientists sent their particular instrument to find out life existence on distinct globes. It was actually a long-armed lander which was sent to Mars in 2007. We can see numerous similar efforts which are being made throughout the world to discern is there life on other planets?

Each day, nature enthusiasts are finding out unique kind of creatures around the world. These inimitable and astonishing and living things reveal that there must be something more living on other planets. However man has to find out where they do exist and how they are surviving in complex and insufferable circumstances?

One who created the life on earth can create it anywhere else. According to human psyche, there must be some necessities on other places rather than earth to have living organism growing. No doubt, oxygen is compulsory for it but hydrogen, carbon, nitrogen and few more particulars play important role in life to survive anywhere like it does on the earth… Not just these elements are required for existence but life needs protection from probable threats such as, bacteria and microbes which prohibit being.

All these facts literally deny life signs on other planets yet. And if scientists happen to get hardly any sign they are still unconscious about how life may survive in unbearable state of affairs…
