Wow! (above) Yes, because of the accuracy of CMBR (cosmic microwave background radiation) the universe can be dated by known science.If you look at Chronology of the universe - Wikipedia , you will find an explanation of how it happened. During the electroweak epoch (between about 10^-32 and 10^-12 seconds after the beginning) the universe consisted of a hot quark-gluon plasma, with interactions between W and Z bosons and Higgs bosons. During this time, fermions and electroweak bosons were massless. During the subsequent quark epoch (10^-12 to 10^-5) seconds, fermions acquired mass, but energies were still too high for quarks to bind into hadrons. Production of hadrons (including protons and neutrons) began during the hadron epoch (10^-5 to 1 second).
By about ten seconds after the beginning, when the temperature had fallen to about a billion Kelvin, protons and neutrons were able to combine into the first atomic nuclei (hydrogen, deuterium, helium-3, helium-4 and lithium-7). The universe was still too hot for electrons to combine with atomic nuclei to form atoms; this had to wait until about 370,000 years after the beginning, when the temperature had fallen to about 4000 K.
Isn't this a more detailed account of the origin of matter than the statement that 'God created the heaven and the earth'? Doesn't it give a better explanation of the observed abundances of the light elements (hydrogen, helium and lithium) and of the cosmic microwave background?
I would like to add a little as to 'How' God created...... at Psalm 104:30 notice God sends forth His spirit to create.
At Isaiah 40:26 God supplied the abundantly needed Power and Strength (His dynamic energy) to create the material realm of existence.
P.S. Genesis is more about getting the existing Earth ready for humankind to inhabit the Earth.
