The Creation of Adam, painting by Michelangelo in the Sistine Chapel at the Vatican, Rome (Wiki)
It´s quite interesting to study the different versions of Genesis. Every culture has one. The name Genesis means "origin". The creation of the world is described in an ancient Greek genesis, Gigantomachie which says that in the beginning there was Chaos. It matches Galia (the Earth), Tartaros (the Nether World) and Uranos (the sky) - All text sources are taken from the "Antikensammlung am Königsplatz", "The Antique Collection at Königsplatz" Munich. Presumably in that very first moment, matter existed in a chaotic form. Chaos means disorganisation and confusion.
In the first chapter of The Bible, Genesis states: "Then God commanded: Let there be light and there was light." A physicist might say, "In the beginning there was Energy" instead of using the word light. Famous physicist Hawking might say "In the beginning everything was information".
The old myth of the Creation of The Universe, is not at odds with the scientific knowledge which we may now have. On the contrary, the standard model of cosmology says that the Universe was created in a single moment, a certain point called the Big Bang. (This model isn‘t without its detractors). The Universe started from nothing and can be dated back 14 billion years. At that point, Space and Time began, as did the Laws of Nature which now regiment the entire Universe. The density of energy was very high, creating the high temperature of ions, the first particles. Molecules did not yet exist, nor even atoms. However, Space cooled quickly because of the rapid expansion and strangely, this expansion seems to continue today and is accelerating.
In the late 20th in the last century, Edwin Hubble discoverd a relationship between the distance of galaxies and the so called Red Shift of light. For astronomers the Red Shift was proof of the expansion of the universe and also proved both its acceleration and the theory of the Big Bang. This permanent expansion and the existence of black holes is one of the deepest secrets of the Universe.
