Creation of the world in Christianity

The central dogma in Christianity is creation from nothing ("Creation ex Hihilo"). According to the central statement the Creator divided matter from nothing and turned it into the material world. This was the free choice of the God and nobody made Him do that because He was filled with love.
The process of the world creation is described in the first chapters of the Book of Genesis that makes the part of Bible. The majority of Christians believe that all three persons of the Holy Trinity took part in the creation of the world appealing to the fact that the plural is used in the text naming the God. According to theological scientists and authorities of church the creation is not the same as birth because the second person of the Holy Trinity must have the nonmaterial nature. And this detail was the point of discussion between the Arians Christians.
All people are created from two exact people Adam and Eve and there are no other ancestors of people. The world was created obedient to the human being. It was harmonic and realized according to the Bible. And the obvious discrepancy with the historical events Church authorities explain with the fact that the God presented freedom to the created angels and to human being that they used to do evil.
In Catholic understanding the chapters of the Genesis are not taken as the literal description of the process of creation and it is allowed to consider them as allegory. Traditional Lutherans don't take the first chapter of the Genesis literally. The Orthodox Christians suppose to understand "the day" used in Genesis as a long period or stage of the universe creation by the God basing on the Bible hermeneutics.
