No ; thought is not engendered by cosmos, but of exceptional increases of the matter's complexity can lead to activities of transcendent order, which emerge of a singular state : consciousness state,
and some of this activities are said "thoughts", what is very different.
"It's clear that the mental phenomena are rather different of the observable phenomena in brain." ." (cf. Benjamin Libet  - Consciousness : conscious subjective, experience),
for example, cerebral activities's chronologies of transcendent order, are distinct from chronologies which characterize physical behaviors of the neurons.

Thus, for spirit in research of primordial causes, true question is not :
how can a brain produce consciousness ? but, 
how, a comprehension state characterized by some faculties that enable to transcend phenomena and that we qualify "consciousness state",
does it emerge of a brain ?

So, analysis of the psyche and cerebral phenomena necessitate an extreme rigour, semantic and conceptual.
For that, for example, we don't recognize the organs, particularly brain, as "operators", they are means which enable activities and actions.
We also reject the ambiguities as :
"the cerebral processes are causing consciousness state, a state which is characteristic of a superior order.".
What is this order ?

Thus, brain does not make spirit but it enables, to the creative entity, of transcendent order, who animates us, from recognizing herself in spirit (in me, ego, subject),
and besides, from managing the body's dynamics and to have thoughts, numerous and diverse.

That is why, according to us, consciousness state is fruit of creation activities ceaselessly more complex,
of evolutions which lead naturally, to recognition of proto consciousness states.

Nevertheless, let's beware to misleading concepts as notions of "primary consciousness", "perceptive consciousness",…, and "self consciousness".
It is more sensible to speak about " primary consciousness state ", "perceptive consciousness state", ..., and "self consciousness state",
knowing that these consciousness state levels presuppose of ceaseless creative activities of physical order and transcendent order.

Let us insist more.
Certainly it's necessary to know biological characteristics of a brain, to know how it is structured and was structured, …,
however, analysis of this information does not have to mask the essential problem :
what is creative entity who uses it, and by man, can understand world in a coherent way in spite of relative character of the interpretations ?

A vast subject that with regard to consciousness state, naturally must lead us to reflect on nature of faculties that enable interpretation,
But also, on the virtual links associated to the permanent interactions between the body's components, the perceptions, presentiments and feelings :

"Let's take quite simple case of distensions of the bladder and rectum : sensation can become extremely pressing and occupy all our spirit, which becomes then obsessed by an urgent assuagement need. It is so strong as it is difficult to think to an other thing." (Cf. Affective Neuroscience - Jaak Panksepp),
"We could speak about a sensation of thirst when dehydration (of the body) is moderated but it's doubtless that a serious dehydration state provokes a more painful sensation and a strong emotion." (Cf. Physiology of Thirst and Sodium Appetite - James Fitzsimons).

What is domain (field, realm) where are, to potential state, these virtualities ?
Logically, it can be only in abstraction's field where are memorized experiences of the past, judged in present moment to anticipate future, in other words, in a timeless and transcendent domain.
Being timeless and of transcendent order, this domain besides, is singular expression of an universal domain associated with space which contains reality,
a transcendent, universal and unknown domain of scientists, philosophers and theologians, containing all virtualities and potentialities which enable the evolutions of the world's dynamics , and that we named : spacimplicatio.

Facts rich in expectations, because they incite us to believe that during existence, we have a " foot in the reality" and a " foot in eternity " !
