Hey guys... here i came back with the another part of alien existence. first i am very much sorry about late article but searching the aliens is also not a easy job right :D .

Okey, here we start, last time we had discussed about the aliens existence and the ancients aliens visit on earth. Now today we are going to put some light on how they should look like. Sometime i think how they looks like. Are they really green in colour as we have seen in the movies or they are something dangerous with tentacles etc. If the aliens already visited here on earth, than where are their photos. Ok that time, we earthlink did not had the cameras but what about the aliens? They should have the cameras right? So, where are the photos. these are the questions which force my mind to think little out of the box. So, how they should look like?? i am still stuck on it. I started to think little differently, first i questioned myself why we are not noticing the aliens photos. They may have took photos or the picture of them must be painted somewhere on the wall. So, why are not noticing that or are we neglecting that? Then after i thought why we neglect something very important and i realise that we only neglect something important when we doesn’t know about it’s importance. This theory drag me to think little differently about the new face of aliens. May be they doesn’t look like what we have imagine them or they are not so dangerous like we thought. May be they also look same like us. That can be another reason of our negligence.Yeap! you have read it correct, just think about it, if you saw a picture of human painting in the wall, does it going to be breaking news?

Scientists also have came with the different theories about the aliens look. As we know that the looks and the body structures always have the impact of the environment. Environment plays very strong role on the body structure of a creature. Like for the example, if we compare with the people from the cold area like russia to the people from the hot area like South Africa then we’ll get the huge amount of difference between them. In our case we are not discussing the difference of the area or the countries but here we are talking about the different planet which is also unknown.

However, there are 5 general theories about the alien's looks. here are they:

1. JELLYFISH
One of the theories also says that Aliens can looks like the Jellyfish marine type animal. The theory based on the Ocean life of earth. Basically, life of earth started in the ocean and the creature interact to outer environment too. Dr Maggie Aderin-Pocock, who works for space firm Astrium, believes that aliens would be marine-type animals with "pulses of light for communication with other aliens, mouth type openings to scope chemicals from atmosphere for growth and reproduction, bodies that enlarge in sunlight, metallic surfaces for absorbing light, lenses for detailed viewing of their surroundings, orange undersides for camouflage, buoyancy sacks to maintain altitude."

2. BUGS
They can be little as a bugs. But when we talk about the little things and its survivals than we’ll get the clear picture of cockroaches. We know that cockroach can survive in the nuclear reaction and also can live in different environment. So, if the aliens are looks like bugs than it should be like Cockroach. Strong surviving quality with the high intelligence.

3. NON-CARBON LIFE
While most of the life found on planet Earth is composed of carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur, scientists found multicellular organisms that do not need oxygen back in 2010 (only bacteria were thought to have this trait prior). But we are not sure about the aliens, they may have composed by the different elements and it can be anything. For an example it can be silicon based life form and in this case it will be nothing like we have found in the planet earth.

4. CREATURES OF THE EXTREMES: DEEP SEA AND HIGH AIR
For example, in the Discovery Canada show Aliens: The Definitive Guide, Dr. Lewis Dartnell, an astrobiologist at University College London, laid out a few possibilities for aliens that might come from planets unlike our own. Creatures from "water worlds" might develop along the lines of the organisms we find in the bowels of our oceans, and a planet with a heavy gravity could support bigger, larger, and more powerful "flying creatures" that take advantage of the thick and dense atmosphere.

5. JUST LIKE HUMANS
As I have already mentioned above the Aliens may look like us. There are many theories about it. Simon ­Conway Morris, professor of evolutionary ­paleobiology at Cambridge University, thinks that aliens would be "just like humans," not only in appearance and biology but in weaknesses, such as "greed, violence and a tendency to exploit others' resources."

What do u think now, do we know how the aliens looks like after reading all above theories. No we are not even close of it. But there are many things which we have to discuss to know about the aliens and how they look like. There are many things which are beyond the theories and some evidence which shows us how they look like. In my next article i’ll come with the other thing which will give some clear idea about their looks.

Keep thinking…. Madvision.
