How the Universe Came into Existence..

The term nucleosynthesis refers to the formation of heavier elements, atomic nucleiwith many protons and neutrons, from the fusion of lighter elements. The theory predicts that the early universe was a very hotplace. One second after the Big Bang, the temperature of the universe was roughly 10billion degrees and was filled with a sea of neutrons, protons, electrons, anti-electrons(positrons), photons and neutrinos. As the universe cooled, the neutrons either decayedinto protons and electrons or combined with protons to make deuterium (an of hydrogen). During the first three minutesof the universe, most of the deuterium combined to make helium. Trace amounts of lithiumwere also produced at this time. This process of light element formation in the earlyuniverse is called “Big Bang nucleosynthesis” (BBN).

Stellar evolution is the process by which a star changes over the course of time

When a guide leading a group of Catholics was asked for the evidence of this being Peter's house, he replied that it's the largest house in the ruins of Capernaum. When asked if Peter had gotten rich after Jesus ascended to heaven, he replied, "Of course not." Hadn't Peter been a fisherman? "Yes." So why would a fisherman own the biggest house in town?

However, the Big Bang model can be tested further. Given a precise measurement of the abundance of ordinary matter, the predicted abundances of the other light elements becomes highly constrained. The is able to directly and finds a value of 4.6% (±0.2%), indicated by the vertical red line in the graph. This leads to predicted abundances shown by the circles in the graph, which are in good agreement with observed abundances. This is an important and detailed test of nucleosynthesis and is further evidence in support of the Big Bang theory. Had the results been in conflict, it would point to 1) errors in the data, 2) an incomplete understanding of the process of Big Bang nucleosynthesis, 3) a misunderstanding of the mechanisms that produce , or 4) a more fundamental problem with the Big Bang theory.

Fred Hoyle, the atheist British astronomer who formulated the theory of stellar nucleosynthesis and originally coined the term, "Big Bang" on March 28, 1949 had this to say at the end of his career three decades later (Note: There are about 2,000 enzymes in the simplest cell, a bacterium, and 'only' about atoms in the entire universe.):
