The earth life origin is examined again.

Here, we consider the reason which the life generated to the earth 4 billion years ago once again.

Probably, we may presume that there was a certain necessity, since it is hard to think that it is accidental.

The possibility of "the earth life type alien having visited and having done the sowing act" was already described.

"If it is a very low alien about evolution, he would visit to the earth aimed at obtaining leisure, and will have done the sowing act carelessly" is thought.

It is expected that such an alien's feeling is as near as us the human beings.

If it is taken into consideration, we cannot think the place where the earth of 4 billion years ago fitted leisure.

He is the alien of a junior engineer class.

And he visited in order to investigate resources.

Also in this way, it is considered.

However, if there is technology in which movement between fixed stars can be performed, we will guess that they had established element substitution technology.

If hydrogen exists, they can make a required element from it.

Thus, probably, we should think that they did the sowing act by some intentions.

If it is only the purpose which does a physical sowing act, they do not need to visit purposely.

It is only sufficient for business that they send in an uninhabited rocket.

We already described a possibility that it would become tapping of resources of a certain kind to cultivate a life object.

In a calm change which is seen to the earth, it is a question about how much there is any validity.

Moreover, the purpose and meaning of a possibility that they conducted a certain experiment are also unknown, and it is difficult to guess.

Isn't the more practical purpose considered?

We look at the ecosystem of the earth.

It exists systematically from a very primitive organism to the organism which evolved considerably.

A high organism is more superior biologically to a primitive organism.

Therefore, we consider that the evolved high organism ruins the organism which is not so.

However, it has not become so practically.

Why does it bring such a result?

A "life" is one kind.

If it considers like this, we understand it.

In order to save our kind, we have to tell posterity all of our character.

When a certain high organism is exterminated under a certain situation,

If the character before the organism occurs is saved, a "life" can make the organism again near the them.

However, if the former character does not remain, a "life" will become unable to restore it.

For the high organism, the lower organism has a role like insurance in emergency.

The high organism has accomplished evolution, devising so that a lower organism may not be made into an extermination.

It is thought that the system of the food cycle of today was also materialized under such a situation.

A organism makes the directivity stiffen so that it evolves high.

Supposing this function did not exist, possibly the life on the earth had ruined by the large accident which reaches for whether being how often.
