- Let so, - Krajl was not handed over, - but even in this case it could fence a surface plot, destroy there flora and fauna of a planet and to plant terrestrial plants. I believe that gradually these strangers for a planet if so it is possible to be expressed, plants could win the increasing areas.- The assumption on the assumption, - was murmured by Tessa.
- In any case, - continued Krajl, - to sit here and to build every possible hypotheses - absolutely useless employment. It is more reasonable to study this planet so in details, how much it is possible, and from such short distance on which we will manage to be approached. Is better would be to land on a planet surface, of course, if it in general really.
- I completely agree with Fisher, - with amazing enthusiasm have responded to Vu.
- I am a biophysicist, - Merri has told, - and I consider that if on a planet there is a life we should investigate it regardless of the fact that there still can or cannot be.
Tessa Vendel has serially inspected all crewmen, has a little reddened and summarised:
- Apparently, it is our responsibility.
- Than more close we fly up to a planet, - Tessa Vendel has told, - and the more information we accumulate, the we are more confused. Now it is not necessary to doubt that the planet is outwardly lifeless. On a dark hemisphere there are no artificial light sources, on all planet there are no signs of vegetative or any other form of a life.
- There are not no but only evident signs of a life, - has easy objected Vu. - Anyway, on a planet there should be any process supporting constant concentration of oxygen in atmosphere. Unfortunately, I not the chemist and consequently cannot imagine purely chemical process such. Probably, at somebody the hypothesis is in this respect ready?
Without having waited the answer, Vu continued:
- To admit, I seriously doubt, that the most formed chemist could offer purely chemical mechanism. Atmospheric oxygen can be formed only as a result of biological process. Alternative ways are unknown to us.
- We have got used so to argue, - Vendel has interfered, - because we judge, proceeding from our private experience which is limited to oxygen atmosphere of a unique planet - the Earth. It is not excluded that ourselves will sometime laugh at our today's submissions. It can appear and so that the Galaxy teems with planets in which atmosphere there is an oxygen of not biological origin, and us will remember as the odd fellows, gone astray true only for the reason that their own planet was it with a biological source of oxygen.
