“Life did not begin on Earth”

Supposedly, life was brought here from elsewhere in space, a notion known as panspermia.

Supposedly life came from rocks from the outer space, such as Mars fro example. There are a

number of Martian meteorites found on Earth, this backs up the theory that microbes were brought

on Earth from Mars, potentially making us all Martians.

Possible of evidence of life

Several Martian meteorites have been found to contain what some think is evidence for fossilised

Martian life forms.

ALH 84001

Allan Hills 84001 is a meteorite that was

found in Allan Hills, Antarctica on

December 27, 1984. It weights

approximately 1.9 kilograms. Scientists

announced that it might contain

evidence for microscopic fossils of

Martian bacteria based on carbonate

globules. A study in 2005 showed an

analysis of the origin of ALH84001 using

data from spacecraft orbiting Mars. According to the analysis, Eos Chasma in the Valles Marineris

appears to be the source of the meteorite.

“Of the various tests used, three have been shown to be particularly useful:

1)the mm-scale morphology of the objects in question;

2)2) the carbon isotopic composition of organic matter associated with and/or comprising the

fossil-like structures; and

3)3) the chemical (molecular) makeup of the fossil-like objects. In principle, therefore, the

question of biogenicity can be easily answered. But in practice, the answer has proven elusive,

primarily because of a lack of analytical techniques having sufficient power to provide the high

resolution three-dimensional morphological information needed to definitively address the

question, and an absence of means by which to directly link, in individual microscopic

specimens, morphological information to elemental-isotopic and structural-molecular

compositions.”-wikipedia

How the organism might of survived

Ice is thought to have covered the oceans 3 billon years ago (ALH 84001 impacted earth approx.

4.5 billion years ago), as the sun was about a third less luminous than it is now. This layer of ice,

possibly hundreds of feet thick, might have protected fragile organic compounds in the water below

from UV. The cold might have also helped these molecules to survive longer, allowing key reactions

to happen.

Development of the molecules

It is quite likely that those molecules were simply bacteria, which evolved over a period of time, forexample.

Early stage of the bacteria including ability to sense light, and knowing to get away from it.

These group of bacteria then become more likely to survive and pass on their abilities.

Then they started to form eye like holes which grant them colours.

Some bacterias decided that they can not feast only on sunlight, they started to eat other bacterias.

Some bacterias decided to move on to land as the ocean were occupied.
