Extraterrestrials

….not to be confused with extra terrestrials (extra earth inhabitants)…

When most people think of extraterrestrials, they think of UFOs, ray guns, and aliens. Extraterrestrials can be any life form that didn’t evolve from earth; they can range from complex intelligent species to goo in a membrane.

Possible ways life can exist

Scientists can’t really make specific assumptions of life, as it could have evolved from different possible ways in different possible forms. But, one thing we do not about our universe is that: it must obey the laws of science. Therefore, we can make general assumptions.

The river of life

Scientists believe that liquid water might play an important role in the creation of life. Because water is a universal solvent which can dissolve a wide range of chemicals, creating increasingly complex molecules which might form the basis of life. Unlike most solvents water is simple and may exist throughout the universe

The river of … carbon…?

Carbon might have a role in the possible creation of life: because it has four atomic bonds, which gives it the ability to bind with four other atoms and create complex molecules, and then compounds. Carbon also has the ability to form long chains.

The birth of DNA

The very fundamental basis of life found in every known living thing, the DNA, might just be the final piece to the puzzle [of how life could exist]. An alien specie would have some sort of self-replicating molecule, such as the DNA

And there you have it folks, water, carbon, and the DNA is what could be needed for the creation of life. There are space organizations, such as SETI, searching and looking for clues that could lead to the evidence of life. But no significant achievement or progress has been made. All life is precious, regardless of how little and insignificant it may appear. Do not what SETI would do if they found a bacteria on Mars? Tune in soon for types of civilization.
